Enthusiasm among Democratic voters in swing states has risen sharply in recent months, according to a survey released Thursday from Gallup.


Gallup polled the 12 battleground states – Wisconsin, Michigan, Florida, North Carolina, Virginia, Colorado, Nevada, New Mexico, Iowa, Ohio, Pennsylvania and New Hampshire - that President Bush won in 2004 but President Obama won in 2008.
The survey found that 73 percent of Democratic voters in those states are extremely enthusiastic about the election, up from 53 in late June. Among Republicans, 64 percent now say they are very enthusiastic, compared to 55 in late June.
In addition, Gallup found that trend wasn’t specific to the swing states – enthusiasm among all U.S. voters jumped from 43 to 55 percent, with Democrats outpacing Republicans by 9 percentage points nationwide. Democrats gained 19 points in enthusiasm, from 49 to 68, compared to a 10 point gain for Republicans, from 52 to 62.
Some of the gap could be attributed to the Democratic National Convention, which wrapped up on Sept. 6. Obama got a small bump in the polls following the convention, although the daily tracking polls conducted by Rasmussen and Gallup have since returned to their pre-convention levels.
But while the national polls remain tight, Obama seems to be sustaining his slight lead in the 12 swing states that will be critical in determining the outcome of the 2012 election.
According to the Real Clear Politics average of polls, Obama leads by 10 points in New Mexico, 8 in Michigan and Pennsylvania, 7 in Wisconsin, 5 in Ohio and Virginia, 2 in Florida, Nevada and New Hampshire, and 1 in Colorado.
Romney leads by 5 in North Carolina, and Iowa is a tie.
The Gallup national poll of 954 registered voters was conducted Sept. 16-17, and the swing states poll of 1,096 registered voters was conducted between Sept. 11-17.
