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

Over the last month of the presidential campaign, there have been continued surprises (Bernie Sanders, Donald Trump), the relatively expected (Hillary Clinton) and the disappointing (Chris Christie, Rick Perry, and Rand Paul).

With less than 450 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 New Hampshire and Iowa. We also factor in candidates' fundraising numbers released last month and their momentum (or lack thereof) over the past few weeks, especially after the first Republican presidential debate earlier this month.

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