Stephen Colbert ripped into "Morning Joe" host Joe Scarborough on Wednesday night, declaring war over what Colbert called an "infomercial" for Republican Congressional candidate Mark Sanford. Sanford, South Carolina's former Republican governor, is running in South Carolina's 1st District special election against Democrat Elizabeth Colbert Busch, Stephen's sister. Stephen, the faux conservative comedian, was so turned off by the "Morning Joe" interview of Sanford that he did the unthinkable — he endorsed a Democrat.
