That is what one pundit thinks:

President Obama is in a fix over firearms. He needs to win undecided voters in the swing states to be re-elected, but these areas are largely pro-gun. So after years of trying to dodge the issue, Mr. Obama let it slip in Tuesday’s presidential debate that he’d push a gun ban in a second term. It’s a revelation that could sway the election.

Read the whole thing. I’m not sure that his statement is going to sway any voters. I think that most voters who are ardent absolutists about gun rights (like me) were never considering casting their ballot for Obama anyway.
