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.

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