Rudy Giuliani continues to run his campaign as if he already has the nomination locked up. All but ignoring new-kid-on-the-block Fred Thompson, Mitt “It’s not flip-flopping if I changed my mind” Romney, and Mr. Straight-talked-myself-out-of-the-nomination, John McCain, he’s already attacking liberals and specifically Hillary Clinton with the gusto of a general election campaign.

First, on the heels of the General Petraeus ad, he ran an ad of his own (at the same discounted rate MoveOn got and he challenged the New York Times to give him), ripping Hillary:

“Who should America listen to,” the ad asked, “A decorated soldier’s commitment to defending America, or Hillary Clinton’s commitment to defending”

He’s also getting his Halloween outfit on early in Iowa. He’s going as “the liberals worst nightmare” this year. In an ad designed to play up his electablity, he rails on liberals and MoveOn once again:

“ is the most powerful left-wing group in the country,” the ad, which is running statewide, intones. “They spent millions electing anti-war liberals. And publicly brag how the Democratic Party is theirs — bought and paid for. Why is MoveOn attacking Rudy Giuliani? Because he’s their worst nightmare.”

Trick or treat Rudy?
