Confirmed: TX Gov. Rick Perry sent out an endorsement email asking supporters to donate to Doug Hoffman's campaign.
UPDATE: Perry's statement, via Eric Kleefeld at TPMDC:
"There is a reason that our party lost power in Washington DC. A lot of folks went to Congress wearing the Republican jersey, but far too many played the game like Democrats. People around Texas -- and frankly, all around the country -- are fed up with the federal government."
