These Candidates Have the Best Chance of Becoming President


Over the past month of the presidential campaign, we've seen more surprises (Ben Carson, Carly Fiorina, and Bernie Sanders). And we've seen our first exits from the race.

Former Gov. Rick Perry of Texas (R) is out. Gov. Scott Walker of Wisconsin (R), one of the strongest-looking GOP candidates early in the race, is out.

Meanwhile, a group of self-proclaimed political outsiders continues to shake up the races in both parties.

With just more than 400 days until the 2016 election, here's another look at who has the best chance of making it to the White House to succeed President Barack Obama.

Our rankings are based on the Real Clear Politics averages of national polls and those in the first-voting states of New Hampshire, Iowa, and South Carolina. We also factor in candidates' fundraising prowess and their momentum (or lack thereof) over the past few weeks, especially after the second Republican presidential debate earlier this month.

Here's a look at where all the candidates stand.

17. Rick Santorum, Republican, former senator from Pennsylvania

It's easy to forget that Santorum won 11 states in his 2012 primary matchup with Mitt Romney, the eventual Republican nominee — including the Iowa caucus.

That's because so far — even though he is the first candidate to crisscross all of Iowa's 99 counties this time — he hasn't been even a blip on the radar in the 2016 race.

He is facing much stauncher competition this time around, and he has not solved his biggest problem from 2012: money. He raised just over $600,000 in the latest fundraising quarter, the kind of money that doesn't bode well for staying power in a crowded field.

The state that provided his biggest win in 2012, Iowa, also hasn't given him the same kind of love. Despite focusing on the Hawkeye State, he still barely registers in polling there.

16. Bobby Jindal, Republican, Louisiana governor

Jindal not too long ago was one of the GOP's rising stars. But his stock both nationally and in his home state of Louisiana has plummeted over the past few years, as his state has fallen into financial disarray.

The result is what's showing up in polls: He has yet to be able to break out of the bottom of the GOP pack — even with a furious line of attack against front-runner Donald Trump.

Jindal and allied groups did raise $9 million in the most recent quarter, but he has missed out on both prime-time Republican debates.

15. Lindsey Graham, Republican, senator from South Carolina

Graham was the clear winner of the "kid's table" debate in September, but he has so far been unable to build any quantifiable momentum off it.

Graham is one of the more interesting candidates in the GOP field, but he is loathed by a segment of the party's base.

He supports immigration reform more than any other member of the field and spars with Donald Trump's comments on immigration. But far more voters, as polls have shown, have instead rallied around Trump.

14. Martin O'Malley, Democrat, former Maryland governor

O'Malley has watched as Bernie Sanders has rapidly become the progressive alternative to Hillary Clinton, outflanking O'Malley's attempt to outflank Clinton from the left.

He is still not well known nationally, and he has not been able to get his poll numbers up much since entering the race at the end of May.

Of course, as his campaign team will constantly point out, O'Malley has an extremely accomplished record as governor, with achievements — on immigration, criminal justice, gay marriage, and healthcare, among others — that he can legitimately flout to progressive voters.

Check out some facts to know about O'Malley:

But he hasn't been able to break out of the doldrums. O'Malley has to hope, at some point, that Sanders implodes and more progressive types in the base rally around him. A Joe Biden entry into the race would further complicate his picture.

13. Chris Christie, Republican, New Jersey governor

Christie put in a solid performance in the second prime-time Republican presidential debate, as one poll put him fourth among the debate's "winners."

But Christie, whose national status has been in decline for the past 18 months, has failed to build much momentum in the first three months of his campaign.

He does seem to have a clear plan, based on his frequent visits north: He is banking on a win in New Hampshire to jump-start his run to the nomination.

But therein lies a problem: He's just ninth in the Granite State, according to a recent average of polls there. And a lot of similar candidates, including Jeb Bush, Marco Rubio, and John Kasich, are investing significant resources there.

12. Mike Huckabee, Republican, former Arkansas governor

Huckabee has continued an attempt to endear himself to conservative, evangelical voters. He participated, for example, in a rally for Kim Davis, the embattled Kentucky county clerk. But there has been virtually no movement in his poll standing over the past month.

The debate earlier this month continued his inability to garner much buzz in his over four months on the campaign trail. And the first part of his plan — win Iowa — is in serious limbo: He polls just seventh in the Hawkeye State.

11. Rand Paul, Republican, senator from Kentucky

Paul is the unconventional candidate of the Republican field. But he has so far been unable to latch on and break through as a clear top-tier candidate. And his problems have only been exacerbated over the past few months.

Two of his political allies were indicted in a campaign finance fraud scheme in the summer. Paul has been plunging in polls over the past two months, and he did nothing to help his cause in the first two Republican debates.

10. Bernie Sanders, Democrat, senator from Vermont

Sanders continues to make inroads against Democratic front-runner Hillary Clinton, and he now holds a comfortable lead against her in New Hampshire. It's part of a stunning rise that has fueled doubts about Clinton's candidacy.

There are questions about whether he's a legitimate threat in the long haul, though, as well as questions about his viability as a potential nominee in a general election.

But Sanders' campaign alone raised $15 million in the most recent fundraising quarter, more than any Republican presidential candidate. His momentum, and the grassroots support and donations behind it, have evoked comparisons to then-Sen. Barack Obama's rise in 2008.

See some of the huge crowds Bernie's been getting on the campaign trail:

9. John Kasich, Republican, Ohio governor

Kasich was one of the biggest winners of the first prime-time Republican debate in August. His performance in this month's second debate was less memorable, but he continues to make inroads as a candidate.

He remains in strong position in New Hampshire, where he has become a prime establishment candidate to win the state and grab key early momentum.

Those who talk up Kasich believe he is a Chris Christie type without the baggage of the past year and a half — that is, a successful governor with a record to point to and clear bipartisan appeal. He also has a plethora of experience from serving nearly two decades in Congress, including foreign-policy areas and his time as chair of the House Budget Committee.

It remains to be seen whether that same bipartisan brand could hurt Kasich with the GOP base. He is to the left of most GOP candidates on immigration reform, and he expanded the federal Medicaid program under the Affordable Care Act — two issues that could doom him with conservatives.

And he hasn't yet caught on nationally — he's just seventh overall in an average of national Republican voters.

8. Ted Cruz, Republican, senator from Texas

Bloomberg's Al Hunt wrote last month that Cruz may be the most underestimated candidate in the race, carefully laying out a brilliant campaign strategy for the long haul.

Cruz remains in the middle of the GOP pack polling-wise, but his eye-popping fundraising numbers mean he will be a factor for a while.

The senator and allied super PACs raised more than $50 million in the most recent quarter to support his presidential bid, a number that put him behind only Hillary Clinton and Jeb Bush (though Cruz did announce his candidacy before any other major candidate).

7) He played a significant role in the government shutdown of 2013, leading a chorus of Republicans who refused to vote for any plan that kept the federal government running that did not also defund Obamacare. Cruz spend nearly 24 straight hours defending his position, including at one point reading the Dr. Seuss classic "Green Eggs and Ham."

8) His father (left) fled Cuba for the United States, worked in the oil industry and eventually became a pastor. He has made headlines for somewhat inflammatory statements, including telling an audience that President Obama should be sent "back to Kenya."

9) He doesn't believe in climate change, an issue many Democrats have lampooned him for, in part because he leads the Senate's Space, Science, and Competitiveness Committee which oversees NASA.​ During a recent appearance on "Late Night with Seth Meyers" Cruz said "Debates on this should follow science and should follow data. Many of the alarmists on global warming, they’ve got a problem because the science doesn’t back them up."

7. Joe Biden, Democrat, vice president of the United States

Biden would have an uphill battle if he were to enter the race, which is becoming an increasingly likely proposition. But the past month has only boosted his stock as a potential candidate.

Lingering concerns over Hillary Clinton's use of a private email server, plus Biden's perceived legitimacy over Bernie Sanders as a potential nominee, would quickly vault him into the forefront of a hotly contested primary. (Keep in mind that the poll numbers below are from his being a theoretical candidate — he will most likely see a boost if he officially enters the race.)

Biden is also polling better against top Republican candidates than Clinton and Sanders, and a poll out Monday showed he could enter the race as the most popular candidate in the field.

Check out Biden's latest moves as he mulls a run:

As a result, she has continued to surge in national polls as well as in the early states of Iowa and New Hampshire.

Her debate performances have cemented a candidacy that had gained a reliable following among the Republican base since her announcement, as she consistently drew some of the most head-nodding crowds at large GOP summits.

She has experience as an executive that few others in the field can point to, and she has been one of Hillary Clinton's fiercest critics. But she will face a significant test in her newfound position as one of the GOP's top-tier candidates, as she is under increased scrutiny over her rocky record at HP and her day-to-day activities on the campaign trail.

National polling average among Republican voters: 11.6% (3rd)

Already, donors are sending warning signals that he needs to show growth as a candidate or face potential defections. Bush has not yet proved formidable as the front-runner for the nomination that many political observers assumed he would be.

He has seen Donald Trump sap the momentum he had built after his official campaign announcement in June. He's had two middle-of-the-pack performances in the GOP debates. All of it has led to slumping poll numbers across the board — his 17% national average in July has dipped almost 8 points over the past two months.

Bush has showed, however, that he is a dynamite fundraiser, as his campaign and allied groups combined raised more than $114 million in the most recent quarter.

4. Marco Rubio, Republican, senator from Florida

Rubio is quickly becoming the establishment favorite for the Republican nomination.

He's a younger alternative in the Republican crowd, and he counts supporters among both the establishment and the more conservative GOP base. He has had strong performances in both prime-time GOP debates — particularly in the September affair, after which he and Carly Fiorina have surged.

He and Fiorina have also recently become the only candidates to successfully engage in back-and-forth attacks with Donald Trump.

Like Trump, Carson is a Washington outsider who has shown he can appeal to a broader electorate — though almost no one inside the Beltway believes that he is a serious contender for the nomination.

There's a clear appetite among Republican primary voters for someone like Trump, whose claims about illegal immigration have again inflamed the debate over immigration reform. And with his claim that he is worth more than $10 billion, he will not be pressed for funds. He said he was willing to spend $100 million of his own fortune for the nomination.
