Liberal Group Attacks McCain

Moveon.org is attacking McCain with this ad:

If you ask me, they're doing him a favor.  If there is anything that would rally conservatives to support John McCain, it would be his being attacked by liberals. 

Update:  Congressman John Shadegg writes: 

“I would be happy to pay for any national commentator who called this either ‘grave’ or ‘troubling’ to download the Beach Boys album that includes the song ‘Barbara Ann,’ to his or her iPod, because they obviously need to get a sense of humor.”

Give McCain credit for taking it to Iran.  I might add that Mitt Romney has also done a good job of this as well.  Moveon appears to be afraid of a McCain candidacy -- at least, that's what this attack implies to me ...
