Former Secretary of State Hillary Clinton looks like a strong 2016 presidential candidate, according to a new Quinnipiac University poll.

She "would start a 2016 presidential campaign with enormous advantages," said assistant poll director Peter Brown.

She would defeat three top Republican contenders by sizable margins, the poll found. She beats New Jersey Gov. Chris Christie, 45-37 percent; Florida Sen. Marco Rubio, 50-34 percent and Wisconsin Rep. Paul Ryan, 50-38 percent.

Vice President Joe Biden doesn't fare as well, trailing Christie but topping Rubio and Ryan. Another possible Democratic contender, New York Gov. Andrew Cuomo, is tied with Rubio and trails Christie and Ryan.
