POWER RANKINGS: Here's who has the best chance at being our next president

The Republican and Democratic presidential primaries enter their third month on Tuesday, with dual contests in the state of Wisconsin.

On both sides, there are signals the race could drag on until the very last primary in California on June 7. And for Republicans, at least, the fight could go to the convention floor in July.

Two of their three remaining candidates - Texas Sen. Ted Cruz and Ohio Gov. John Kasich - have mathematically impossible odds of obtaining enough delegates before the convention.

Nevertheless, they are powering on, looking to stop frontrunner Donald Trump from clinching the nomination before the convention. Wisconsin could be a momentum-shifter: Cruz is favored to pull off a victory there.

Meanwhile, the upstart on the Democratic side, Sen. Bernie Sanders, also stands as a slight favorite to upset former Secretary of State Hillary Clinton in the Badger State.

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 in upcoming contests (Wisconsin, New York, and Pennsylvania). 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: Florida Sen. Marco Rubio.

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