Robert Patterson points us to a Quinnipiac Poll that has Hillary Clinton leading both Marco Rubio and Jeb Bush in their home state in a hypothetical 2016 matchup:

Mrs. Clinton, who shows the most strength of any potential 2016 aspirant in Quinnipiac University's national polls, leads Jeb Bush 51 - 40 percent and bests Sen. Rubio 52 - 41 percent in a poll of Sunshine State registered voters.

Clinton is viewed much more favorably than either man, 62 - 33 percent favorable for Clinton, compared to 50 - 35 percent favorable for Bush and 41 - 34 percent for Rubio.

"We probably won't know for some time whether former Secretary of State Hillary Clinton runs for president in 2016, but if she decides to make the race, she begins with a sizable lead in a state that Republicans cannot win the White House without," said Peter A. Brown, assistant director of the Quinnipiac University Polling Institute. "Florida voters have a very positive view of Mrs. Clinton and it's not just Democrats who feel that way."
