POWER RANKINGS: Here's who is most likely to be the next president
April 26 Presidential Power Rankings (BI)
Trump: 'I consider myself the presumptive nominee, absolutely'
5. John Kasich, Republican, Ohio governor
Kasich picked up momentum last month with a win in his home state's primary.
But the road before, and since, has been virtually empty for the Ohio governor. He has no chance to accumulate enough delegates to clinch the nomination before the convention, so he's banking that he can win a floor fight.
Those who talk up Kasich say he is a successful governor of a swing state with a record to point to and clear bipartisan appeal. He also has abundant experience from nearly two decades in Congress, including foreign-policy areas and his time as chair of the US House budget committee.
But that same bipartisan brand has 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 hard-line conservatives.

4. Bernie Sanders, Democrat, senator from Vermont
Sanders had perhaps the best single day of his campaign late last month, romping to landslide victories in Alaska, Hawaii, and Washington. But he got tripped up in New York, with a bigger-than-expected loss to Clinton in her adopted home state.
And he faces challenging odds — he needs to win about 71% of the remaining pledged delegates to overtake Clinton in the pledged-delegate count, according to NBC.
Moving forward, the map doesn't look especially favorable. In a system in which delegates are allocated proportionally, it will be hard for him to make up real ground in large states like California, Pennsylvania, New Jersey, and Maryland.

3. Ted Cruz, Republican, senator from Texas
Cruz always had favorable ground in Wisconsin. After that, the map was supposed to get more challenging — and it has.
Late April has overwhelmingly featured Northeast and mid-Atlantic contests more favorable to Trump — including delegate-rich New York, which Trump won with more than 60% of the vote. With more states from the regions on the map to come, Indiana's May 3 primary is looking more and more like a must-win for the Texas senator.
Still, Cruz inspires a flood of enthusiasm among the GOP base, and he may be the best-positioned candidate from within the political sphere to back up the notion that he's not a typical politician, that he is the outsider the base wants despite his day job in Washington.

2. Donald Trump, Republican, businessman
Trump has lit the political world on fire since his entry into the race last summer, and he has showed surprising staying power. We're now on month No. 11 of "The Trump Show."
He has won a majority of contests so far, a feat unthinkable when he entered the race in June. He appears poised to at least enter the convention with the most delegates of any Republican candidate — and after a gigantic win in New York, he seems better positioned to capture the nomination heading into the convention.
There's a clear appetite among Republican primary voters for someone like Trump, who entered the race to controversy surrounding his position on illegal immigration. Business Insider discovered more of that when we followed him on the trail for a week last year.

1. Hillary Clinton, Democrat, former secretary of state
The delegate math is on Clinton's side going forward, especially now that she has avoided her biggest potential pitfall in the New York primary.
The long-presumed Democratic nominee, Clinton has been a shakier-than-expected candidate. But she has a clear look at the nomination, and she would enter the general election with a slight advantage over Trump — or Cruz.
"I'm not going to be responding to him," Clinton said in a recent interview with Business Insider. "I have pretty thick skin. I've been in the arena a long time, and that means that I am not going to get down with him and go insult for insult."
"They have no path to the nomination," he said. "... They should get out of the race, and we should heal the Republican Party."
Trump insisted that he can unify a Republican Party that seems increasingly divided.
"I'm a unifier. I unify people," he said. "That's how I did it in business. ... We will have people that are backing this party and backing my candidacy that you wouldn't believe. We're going to have such unity."
On Sunday, Kasich and Cruz announced an alliance to essentially halt campaigning in certain states where the other candidate has a clear advantage in an attempt to block Trump from winning the nomination.

If Trump does not reach the 1,237-delegate threshold, he could run into problems attempting to secure the nomination. Cruz has continually outmaneuvered Trump in electing delegates to the Republican National Convention. If Trump does not win 1,237 delegates, many convention delegates would become "unbound" to Trump in later rounds of convention voting, giving Cruz or Kasich a likely boost in support.
