Former Secretary of State Hillary ClintonHillary Rodham ClintonLabor chief: Clinton-Lynch meet not ‘planned in advance’ Clinton scheduled to interview with FBI: reports Dem platform draft adopts Sanders proposal on taxing foreign earnings MORE leads three potential 2016 Republican presidential contenders in a new poll.
In the new Quinnipiac poll of registered voters nationwide, New Jersey Gov. Chris Christie (R) fares the best against Clinton, taking 37 percent support to her 45 percent support.
But against the other two potential Republican candidates tested, Sen. Marco RubioMarco RubioRubio: Clinton-Lynch meeting ‘raises all sorts of red flags’ Which GOP pols will actually attend the convention? Poll: Rubio holds massive lead in primary MORE (R-Fla.) and Rep.

But a handful of other Democrats, including Vice President Biden and New York Gov. Andrew Cuomo, are also considering a run.
Quinnipiac tested both Biden and Cuomo against the three Republicans, neither of whom are able to topple Christie.
The New Jersey governor leads Biden by 3 percentage points, with 43 percent support to Biden's 40 percent support, while Biden has the same edge against Ryan, with 45 percent support to Ryan's 42 percent. Biden leads Rubio by 7 percentage points.
And Christie takes a double-digit lead over Cuomo, who seems to suffer from a lack of name recognition, as he holds the highest percentage of undecided respondents in his match-ups. Ryan, too, leads Cuomo, by 5 percentage points, while Rubio ties him, both with 37 percent support.
Quinnipiac University surveyed 1,944 registered voters nationwide from Feb. 27 to March 4, and the poll has a margin of error of 2.2 percentage points.
