Euphememism, Schmeuphemism

The blurb from the New York Times email update this morning linking to this story:

Gov. Arnold Schwarzenegger’s centrism in California appeals less to the Republican Party’s base than the resistance push of Senator Mitch McConnell of Kentucky.

I'm no McConnell Republican, but if Schwarzenegger Republicanism means "centrist," "centrist" must mean "ideologically bankrupt."
