The constitutional amendment to ban same-sex marriage in Florida needs a 60 percent voter approval to pass. According to the new Quinnipiac University poll, Florida voters support an amendment that would define marriage as being between a man and a woman, 55 to 41 percent. That's slightly lower than the 58 to 37 percent support in a June 3rd survey.

Republicans support the amendment 76 to 21 percent, while Democrats oppose it 51 to 45 percent and independent voters oppose it by a similar 51 to 44 percent margin.

An assisting director for the polling institute says the 55 percent overall support for the same-sex marriage ban is a bit surprising, especially given that similar amendments have already passed in a dozen other states. But you can bet backers of the amendment will use the next eight weeks leading up to the November election to try and close that five point gap.

The poll also reveals Governor Crist retains his 61 to 25 percent job approval rating.
