(AP Photo/Bruce Smith) (Newser) – Well, this can't feel great: The Democrat who opposed Elizabeth Colbert Busch in the primary for a vacant congressional seat has endorsed her Republican opponent, former South Carolina Gov. Mark Sanford. Ben Frasier got only 4% of the vote last month against Colbert Busch, the sister of political satirist Stephen Colbert. Frasier says that he's a conservative Democrat and that Colbert Busch doesn't represent the district's conservative values. Colbert Busch faces Sanford and Green Party candidate Eugene Platt in next month's special election.
