Attack attention

In the race for the Republican presidential nomination, second tier candidates have finally drawn some attention -- for relentlessly attacking each other.

Leaving the frontrunners Giuliani, Romney, and McCain to squabble amongst themselves, Sam Brownback and Mike Huckabee are going at it. Early this week, a Huckabee surrogate derided Brownback for converting to Catholicism. The two campaigns have traded barbs, and now the Club For Growth is attacking Huckabee with an ad in Iowa.
