John McCain's ad and speeches that claim Obama supports sex-ed of kindergartners, called Sarah Palin a pig, as well as the repeated claim that Palin told Congress "no thanks" to the Bridge to Nowhere have raised some eyebrows.

McCain's campaign has explained its tactics [1] confessing that when McCain played nice in 2000, he lost. McCain's spokesman said: "Clearly we intend to stay on offense . . . because the campaign is fundamentally about him (Obama). We feel comfortable about the ads we’re running and arguments we’re making.” Well the tactic makes someone unlikely uncomfortable: Karl Rove.

Rove told Fox News Sunday [2] that both have gone too far. He said Obama's ad claiming that McCain cannot send email is unfair because McCain's war injuries prevent him from typing. (McCain did say a few months ago that he's learning to use a computer.)

About McCain, the former brain of Bush said: "McCain has gone in some of his ads —similarly gone one step too far, and sort of attributing to Obama things that are, you know, beyond the 100-percent-truth test. They don't have to attack each other this way. They have legitimate points to make about each other." The Obama camp piled on Rove's admission, saying: "In case anyone was still wondering whether John McCain is running the sleaziest, most dishonest campaign in history, today Karl Rove — the man who held the previous record — said McCain's ads have gone too far."
