Rubio leads both Democratic candidates, according to a Quinnipiac University poll released Wednesday.


Rubio initially said he would not run for reelection but has now decided to seek a second term.

Rubio has 47 percent support, to 40 percent for Rep. Patrick Murphy (D-Fla.) if the two face off in the Senate race.

The Quinnipiac survey offered good news for Republicans in other Senate races.
