He Didn't; He Did

Mitt's message is that he has no influence on what PACs do.  According to the Post-Gazette, Mitt flip-flops on whether or not he even sees the PAC advertisements.

Mr. Romney said: "With regards to their ads, I haven't seen them. And, as you know, under the law, I can't direct their ads." A moment later, Mr. Romney acknowledged that he had, in fact, seen the ads and he recited a few of their messages.
