Obama leads in polls following Romney gaffes
Mitt Romney's latest gaffe has given President Barack Obama's post-convention lead in the polls a little more strength.
Obama is leading in several surveys released days after a video showing Romney talk to donors surfaced.
The GOP contender went on the defensive after he told the group during the May event that he couldn't win over the 47% of Americans who don't pay income tax.
