WASHINGTON – Republican National Committee Chairman Ed Gillespie called on the nine Democrat presidential candidates to repudiate an ad posted on the Moveon.org website comparing President Bush to Adolf Hitler.

The ad has since been removed from the website.

Adolf Hitler

“This is the worst and most vile form of political hate speech,” said Gillespie. “These candidates have a chance to repudiate this pollution of our political process by repudiating these ads at this afternoon’s debate in Iowa.”

Gillespie told Fox News Sunday the Move On organization, supported by billionaire George Soros, plans to spend millions to defeat Bush this year.

Move On sponsored a television ad contest for the best anti-Bush spot.

“One of the ads that was submitted that they considered viable for airing – with $7 million, by the way, in funds that we don’t know where it comes from, but we know they’ve said they’d spend $7 million to air the ad that they’ve settled on – one of them morphed President Bush into Adolf Hitler,” explained Gillespie. “Those are the kind of tactics we’re seeing on the left today in support of these Democratic presidential candidates.”

The ad shows a series of pictures of Hitler speaking in German. Text on the screen reads as follows: “We have taken new measures to protect our homeland … I believe I am acting in accordance with the will of the Almighty Creator … God told me to strike at al-Qaida and I struck them … and then He instructed me to strike at Saddam, which I did.”

“Sound familiar?” asks the text, to the sound of cheering Germans.

In November, Soros compared Bush to Hitler in an interview with the Washington Post.

Saying he believed the White House was guided by a “supremacist ideology,” Soros complained: “America, under Bush, is a danger to the world … When I hear Bush say, ‘You’re either with us or against us,’ it reminds me of the Germans … My experiences under Nazi and Soviet rule have sensitized me.”

Soros, a Hungarian emigre, announced before the interview was published he was donating $5 million to Move On, the organization’s single biggest contribution ever.
