(SOUTH FLORIDA SUN-SENTINEL) TALLAHASSEE — A Quinnipiac University poll released this morning shows Republican presidential hopeful Mitt Romney pulling ahead of President Barack Obama in Florida.

The poll shows Romney with a 47 percent to 41 percent lead over the president. The move signals a shift from the statistical dead heat in a poll conducted two weeks ago and one in March that gave the president a 49-42 percent lead.

One reason for the shift could be the president’s recent vocal support of same-sex marriage. According to the poll, 25 percent of voters said his support of the issue made them less likely to vote for him. However, 63 percent said it made no difference.
