Is Sanford really unpopular? I never heard anything negative after a week or so during his scandal. Peter McCoy is running and he's my state rep, so I may vote for him over mark. I'm not real sure. Or I'll back Colbert for the lolz.
Colbert-Busch is running as Democrat, so she isn't in the same primary as Sanford. (BTW she pronounces the family name Col-bert, not Col-bear as her brother does. If
Keeping Up Appearances does a 25th Anniversary show, he should be the host for the US version.) It helps that Sanford is engaged to his Appalachian sweetheart now, but it's still a liability. Unless he ends up facing a real stinker of an opponent in the runoff, I expect him to make the runoff, but lose it.
