A new poll shows New Jersey Gov. Chris Christie (R) in a virtual tie with former secretary of state Hillary Clinton in a potential 2016 matchup.

The Quinnipiac University poll shows Christie at 43 percent and Clinton at 42 percent.

It comes as Christie's landslide win in his reelection campaign last week has led to increased speculation about his 2016 prospects. An NBC News poll last week showed Christie trailing Clinton 44-34 but doing well among several key demographics, including Latinos and young people. (NBC's sample was among all adults while Quinnipiac's poll is among registered voters.)

The Quinnipiac poll also shows Christie doing well among Latinos, trailing Clinton just 46-38. GOP nominee Mitt Romney in 2012 took just 27 percent of the Hispanic vote.

Christie also has some crossover support. Nearly four in 10 Democrats (37 percent) say he would make a good president, including 36 percent of self-described liberals.

No other Republican comes close to Clinton, with Rep. Paul Ryan (R-Wis.) and Sen. Rand Paul (R-Ky.) both trailing Clinton 49-40 and Sen. Ted Cruz (R-Tex.) trailing 51-36.

The poll is not kind of Vice President Biden. While Biden is reasonably well-liked as vice president, the poll shows 65 percent of people say he would not make a good president (versus 25 percent who say he would). Nearly four in 10 Democrats (38 percent) say he would not make a good president.

Biden has made it clear he has designs on running for president in 2016.
