I wanted to point to an article in The Atlantic that says that over a longer period gaffes don't affect poll results. So while it's good to see Romney messing up, it's not a reason to lay back and stop working for Obama. We 6 weeks left and we need to use each one of them to get out the vote and not sit back.
