The answer to DougJ’s question is simple– the people who read Kaus are Republicans who can cite his union bashing, anti-immigrant and other right-wing views and say “even the liberal Mickey Kaus.”
That is his only purpose. He’s a one man New Republic. Expect his candidacy to be used to portray Boxer as an extreme leftist by DeVore.
It really is that simple.
BTW- I’ve decided I’m not running for Congress, so I expect to have a NY Times editorial any day now.
