Poll: Obama leads in swing-state Florida

Obama leads Romney 50 to 46 percent, which is mostly unchanged from the same poll in April, when the president led 50 percent to 45.

While Romney’s favorability rating has spiked in some recent national polls, he continues to be viewed negatively by voters in Florida. Romney’s favorability rating is at 39 percent, versus 53 unfavorable. Obama is at 49 favorable and 46 unfavorable.

Obama’s base of Hispanics, women, young voters and African-Americans buoyed him in the poll, while seniors and whites favored Romney.

Obama would still lead by 3 to 5 points if Romney were to add Sen. Marco RubioMarco RubioRubio: I hope I can trust whoever wins with the nuclear codes Rubio faces Trump-like challenger in primary Rubio on VP: 'It's too late for that' MORE (R-Fla.) or former Gov.
