A new poll from Quinnipiac University shows former secretary of state Hillary Clinton (D) and New Jersey Gov. Chris Christie (R) start as their parties' top prospects for president in 2016.

Clinton leads all comers in prospective matchups against three Republicans -- Christie, Sen. Marco Rubio (R-Fla.) and Rep. Paul Ryan (R-Wis.):

Clinton 45, Christie 37

Clinton 50, Rubio 34

Clinton 50, Ryan 38

In matchups with Vice President Biden (D) and New York Gov. Andrew Cuomo (D), though, Christie comes out on top:

Christie 43, Biden 40

Christie 45, Cuomo 28

Here are the other matchups:

Biden 45, Rubio 38

Biden 45, Ryan 42

Rubio 37, Cuomo 37

Ryan 42, Cuomo 37

It's still extremely early, of course, and these numbers likely reflect how well-known these politicians are (or aren't) more than anything else. Clinton left office very popular, but she's also better-known than anyone else, except perhaps Biden.

Rubio and Cuomo, in particular, aren't as well known as the other names on this list, which is likely why they fare so poorly.
