POWER RANKINGS: Here's who has the best chance at being our next president
Tuesday could be the day that defines the rest of the presidential primary race.
It could be the last shot for Republicans to stop their party's presidential frontrunner, Donald Trump.

It could be a chance for Bernie Sanders to gain momentum against Hillary Clinton on the Democratic side, or for Clinton to again show her strength by piling up a near-insurmountable delegate lead.
Republican and Democratic voters in five states will head to the polls Tuesday night with a swath of delegates at stake in each race.
Trump is looking for the "knockout blow" -- wins in the winner-take-all states of Florida, which awards 99 delegates, and Ohio, which allocates 66 delegates. It would provide him with a very clear path to the 1,237 delegates needed to clinch the nomination.
On the Democratic side, Clinton is aiming to bounce back after a stunning loss to Sanders in Michigan. She remains the Democratic frontrunner and leads Sanders by more than 200 pledged delegates.
With all that in mind, we take 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 states voting Tuesday (with the exception of Missouri, which has not been polled in months). We also factored in the candidates' delegate counts and their relative paths to the nomination, as well as their momentum (or lack thereof) over the past few weeks.
Since our most recent ranking, one more Republican candidate has dropped out of the race: retired neurosurgeon Ben Carson.
Here's a look at where all the candidates stand.
