The McCain camp released this one yesterday:
Not an unfair ad, though I think McCain is treading in dangerous waters by inviting Obama to respond in kind. There is a very long history of Republicans with established conservative credentials saying awfully harsh things about John McCain. From campaign finance reform to immigration to tax policies to even abortion policies, there is an ocean of anti-McCain rhetoric from pols and pundits who have enjoyed much greater respect from the GOP base than John McCain over the last 10 years. Hopefully Obama takes the queue.
