KING OF THE NUTJOBS…. In the ongoing contest to see which House Republican is the single nuttiest, Rep. Steve King (R) of Iowa is making another run at the title.

The Madman from the Heartland has had quite a week. On Monday, King told The Hill that the best vote he ever cast was to deny emergency aid to the Gulf Coast after Hurricane Katrina struck in 2005.

On Tuesday, he appeared on a conservative talk show and said marriage equality is part of a broader “push for a socialist society.” King added, “Not only is it a radical social idea, it is a purely socialist concept in the final analysis.” I guess that means gay bureaucrats control the means of production?

He kept things going yesterday on the House floor, standing alongside Socialist Realist art to argue that President Obama is the leader of ACORN.

Today, however, was my personal favorite. King is apparently angry — it’s not clear why — that President Obama is changing U.S. missile-defense policies in Europe. The White House is scrapping a Bush-era policy that didn’t make sense, for a more effective anti-missile technology, with a better track record, and more flexibility, which will be implemented sooner. The move was endorsed by the Secretary of Defense and backed by the unanimous judgment of the Joint Chiefs of Staff.

King initially said the president is honoring the “Neville Chamberlain school of diplomacy or capitulation.” The Iowa Republican added, “I was thinking about the situation of how it was that Hitler actually negotiated with the Russians for a while. It ended up with Poland being divided and a global war as a result.”

So, as far as King is concerned, Obama is both Chamberlain and Hitler?

For that matter, if negotiating with Russia makes one Hitler-like, what does King have to say about Reagan holding talks with Russia — when it was the Soviet Union?

Look out, Michele Bachmann. Steve King has his eyes on your crown.
