The very Obama friendly Politico reports:

President Obama’s same-sex marriage endorsement makes a full quarter of Florida voters less likely to cast their ballots for him, according to a poll released Monday.

Quinnipac’s latest poll of the Sunshine State finds that 25 percent of voters say Obama’s endorsement of gay marriage makes them less likely to vote for him. On the other hand, 11 percent say that it makes them more likely to vote for him.

Among independents, 23 percent say that they’re less likely to vote for Obama over same sex marriage. Older voters (55 and older), born-again evangelical Christians, lower income voters and military veterans are all more likely than other demographic groups to say that Obama’s backing of same-sex marriage will sway them towards Romney.

On the whole, Romney beats President Obama by six points in Florida, leading 47 to 41 percent over the incumbent president.
