In fewer than 70 days, the first votes of the 2016 presidential primary will be cast.
The last month in the respective Republican and Democratic primaries have taken distinctly different turns.
Since Vice President Joe Biden declined to enter the race, former US Secretary of State Hillary Clinton has cemented herself as the clear Democratic front-runner.
The Republican field, meanwhile, has something of a "free-for-all" feel. A man who was long expected to fade by now, real-estate tycoon Donald Trump, continues to lead almost every national and early-state polls.
Behind him is fellow political "outsider" Ben Carson, the retired neurosurgeon, and three other, more experienced candidates: US Sens. Marco Rubio (R-Florida) and Ted Cruz (R-Texas) and former Florida Gov. Jeb Bush. The feeling is that a slew of candidates in the still-crowded field can win.
So with less than a year until Election Day 2016, here's another look at who has the best chance of making it to the White House to succeed US 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 each party's debates earlier this month.
Here's a look at where all the candidates stand.
(All poll results as of Monday.)

15. Rick Santorum, Republican, former senator from Pennsylvania
It's sometimes 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 he still hasn't even been a blip on the radar in the 2016 race.
He is facing stauncher competition this time around, and he has not solved his biggest problem from 2012: money. He raised less than $400,000 in the latest fundraising quarter and had just more than $200,000 cash on hand, 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, placing 11th in an average of recent polls. He has lingered around that level since he entered the race.
National polling average among Republican voters: 0.5% (12th)
Iowa: 1.3% (11th)
New Hampshire: 0.6% (12th)
South Carolina: 0.5% (12th)
STOCK: Neutral

14. Lindsey Graham, Republican, senator from South Carolina
Despite seemingly increased exasperation at some of the names ahead of him, Graham continues to be an afterthought in the race.
He hardly registers in Iowa. He barely shows up in New Hampshire polling. In his home state of South Carolina, he's just seventh in a crowded field.
The Republican base has soured on Graham's support of immigration reform and his distinct split from Trump on the topic. Far more voters, as polls have shown, have instead rallied around Trump.
"Donald Trump is the most uninformed person I've ever met running for president when it comes to foreign policy," Graham said recently. "He has no clue of what he's talking about. He doesn't understand how to destroy ISIL. ... President Obama doesn't have a clue of what he's doing. Don't replace President Obama with Donald Trump. It will get worse, not better."
National polling average among Republican voters: 0.8% (T-11th)
Iowa: 0.7% (12th)
New Hampshire: 0.8% (11th)
South Carolina: 2.3% (7th)
STOCK: Neutral

13. Martin O'Malley, Democrat, former Maryland governor
O'Malley has watched as Bernie Sanders has entrenched himself as the progressive alternative to Hillary Clinton, outflanking O'Malley's attempts to outflank Clinton from the left.
Despite a vigorous campaign schedule, O'Malley is still not well-known nationally, and he has been unable to boost his poll numbers even in a three-way race.
O'Malley has an accomplished progressive record as governor, with achievements — on immigration, criminal justice, gay marriage, and healthcare, among others — that he can legitimately tout to Democratic voters.
But he hasn't been able to break out of the doldrums, even with solid performances in the first two Democratic presidential debates. O'Malley recently shifted more of his campaign staff to Iowa, where he'll need a strong showing to continue on the trail.
National polling average among Democratic voters: 4.4% (3rd)
Iowa: 4.5% (3rd)
New Hampshire: 3.7% (3rd)
South Carolina: 2.7% (3rd)
STOCK: Neutral
