Clinton has not announced a 2016 candidacy for the White House, but is seen as the overwhelming favorite to win the Democratic nomination if she chooses to run.
The Quinnipiac poll suggested she'd be a stronger candidate for Democrats in Florida than Vice President Biden, who trailed Bush and Rubio.
Rubio remains fairly popular in Florida — 51 percent approve of the job he's doing, while 35 percent disapprove. But constituents don't view his handling of immigration issues as positively. According to the poll, 41 percent disapprove of the way he's handling the issue, while 33 percent approve. Those numbers are better with Republicans, with 52 percent approving of his work on immigration while 24 percent disapprove.
