PRESIDENT:

I know everybody is predicting a nasty election, and thankfully, we’ve all agreed that families are off limits. Dogs, however, are apparently fair game. (Laughter.) And while both campaigns have had some fun with this, the other day I saw a new ad from one of these outside groups that, frankly, I think crossed the line. I know Governor Romney says he has no control over what his super PACs do, but can we show the ad real quick? (Video is played.) (Applause.)

That’s pretty rough — (laughter) — but I can take it, because my stepfather always told me, it’s a boy-eat-dog world out there. (Laughter.)
