The strongest Republican in the state is Carson, who leads Clinton 49/40 and Sanders 48/33. Carson easily has the best net favorability rating with the overall electorate- +20 at 45/25. The second strongest polling Republican is actually Trump who leads her by 6 at 48/42 and who has a similar 47/41 lead over Sanders. Biden polls a tick closer to Trump, trailing by 4 at 47/43. Also leading Clinton by decent sized margins are Fiorina (46/41) and Rubio (48/43). Fiorina (37/31) and Rubio (44/43) join Carson in having positive favorabilities with the full voter pool.
The other general election match ups with Clinton are close. She trails Jeb Bush 45/42, with Biden and Sanders down by similar margins as well. Bush's not polling as well against the Democrats as some of the other Republican candidates is a reflection of his overall unpopularity in the state- only 36% of voters see him positively to 52% who have a negative opinion. Clinton is down 44/41 to Kasich and 45/43 to Walker. The two Republicans who trail Clinton in Florida are Cruz and Huckabee, both at 45/43."
