Trump is leading the GOP presidential primary race in Florida with 21% of support compared to Bush's 17%, according to a Quinnipiac University poll released Thursday. Florida Sen. Marco Rubio
also trails both Trump and Bush, tying retired neurosurgeon Ben Carson
with 11% among registered Republican voters.
The Quinnipiac survey also shows Vice President Joe Biden, who is still mulling a presidential run
, is running equal to or better than Hillary Clinton
against the top Republican contenders in Florida, Ohio and Pennsylvania, three key general election swing states.
Biden came out ahead of Trump, the Republican front-runner, by 3 points in Florida, 10 points in Ohio and 8 points in Pennsylvania.
Clinton, by contrast, trails Trump by two points in Florida and leads the businessman by 5 points in Ohio and 5 points in Pennsylvania, according to the poll.
Despite their front-runner status, Trump and Clinton top the list of candidates with the worst favorability ratings in the three swing states. They are also perceived as the least honest and trustworthy of all the candidates in those states; more than half of voters in the three states have a negative view of Clinton and Trump.
In Pennsylvania, Trump came out ahead of the rest of the GOP field, registering 24% of support -- double digits ahead of his closest competitors Bush and Rubio who notched 13% and 10%, respectively, according to the Quinnipiac poll.
Ohio Gov. John Kasich retained his home state advantage with 27% of support, according to the poll, but Trump trails closely behind with 21%.
