A shift by independent voters gives President Barack Obama the lead over Republican Mitt Romney in Florida, according to a new Quinnipiac University poll. Mr. Obama now claims 46% of the Florida vote to Romney's 42%.

In May, a majority of independent voters supported Romney in Florida by a margin of 44% to the President's 36%. Today, 46% of Independents support the President compared to 37 % for Romney.

There are a few constants. The President carries a majority of women, African-Americans, and voters 18 to 34 years old. Romney carries a majority of white voters and voters over 55 years old.

48% of voters say Romney would do a better job on the economy, compared to 44% who say the same for the President. Voters are on who would create more jobs. Meantime, 49%  of Florida voters say the President would do more "to advance the economic interests of middle class Americans" compared to Romney's 44%.

The same Quinnipiac University Poll signals a tight race in the Florida Senate as well. U.S. Representative Connie Mack has an overwhelming lead over the Republican field. However, the democratic incumbent, Senator Bill Nelson, leads him by a nose, 43% to Mack's 39%.

In May, Nelson and Mack were in a virtual tie, 42% to 41% respectively.
