Once again, Tom Davis proves why he is one of my all-time least favorite Republicans. According to the Washington Times:

Rep. Thomas M. Davis III, the Virginia Republican who has assumed leadership of his party's more liberal members of Congress, said yesterday that conservative groups such as the Club for Growth are hurting the party by refusing to help candidates who don't pass their "litmus test" and by attacking some incumbent Republicans.

Bottom line: The Club for Growth is one of the most effective conservative groups in America.
