Governor Mark Sanford’s South American enterprise to see his mistress this week was the most unbelievably foolish stunt we’ve seen a politician undertake for the sake of adultery in recent memory… wait… that just really isn’t the case. Oh well – it was still incredibly ill advised. Anyway, before Argentina happened, Governor Sanford was being highly touted as a potential presidential candidate three years hence. Now, that isn’t going to happen. This situation reminds us that there are different standards for Democrat and Republican candidates. Put a different way, there are standards for Republican candidates and no standards for Democrat candidates (see W.J. Clinton, Teddy Kennedy). So who’s left on the Republican chief executive smorgasbord? And what will push each of them toward and hold them back from the right to challenge the venerable and serene President Barack Obama?
