4. Mark Sanford « The Washington Independent
Remember when Gov. Sanford (R-S.C.) was regarded as a potential 2012 candidate? That was at the start of this year, when he was head of the Republican Governors Association, drew national attention for opposing the stimulus, and was generally laying the groundwork for a presidential run. But a bizarre scandal destroyed Sanford’s hopes for a future at the White House. His closest advisers were left scrambling to explain his whereabouts this past summer, first telling the public that Sanford was hiking the Appalachian Trail. Sanford later admitted he was having an extramarital escapade in Argentina. He soon resigned from the RGA and faced calls to step down from office. But he has refused to throw in the towel and continues to serve as governor.
