McCain Has Challenger, If We Use The Term Loosely

Politico is reporting that Chris Simcox, founder of the Minutemen Civil Defense Corps, wants to challenge Sen. John McCain in the 2010 GOP primary:

Social conservatives tolerated John McCain as the party's nominee, but never trusted him, and he now appears to be facing a serious primary from the right in Arizona next year.

Chris Simcox, the founder of the Minuteman Civil Defense Corps and a prominent figure in the anti-immigration movement, will announcing tomorrow at an event on the Mexican border that he's resigned from the group to run in the 2010 Senate primary.

We're skeptical that "serious primary" is an accurate assessment.
