POLL: Obama Leads in FL, OH, PA

TPM Elelection Central has this report on a Quiinnipiac poll which shows that Barack Obama is leading John McCain in three "swing states" of Florida (27 electoral votes), Pennsylvania (21 electoral votes) and Ohio (20 electoral votes). In 2004, if John Kerry had won Ohio he would have been elected president.

Florida
Obama (D) 47%, McCain (R) 43%
Margin of error: ±2.6%

Ohio
Obama (D) 48%, McCain (R) 42%
Margin of error: ±2.6%

Pennsylvania
Obama (D) 52%, McCain (R) 40%
Margin of error: ±2.5%

This is the first poll to show Obama leading in Florida. If the election were held today, Barack Obama would be elected President. Unfortunately, exactly four years ago, John Kerry was also polling ahead of George W. Bush (and we all know what happened in November 2004!)
