Since this is from the notorious South Carolina right-wing blogger and Nikki Haley tormenter Will Folks, you can take it with a grain of salt, but FITS News reports internal polling from the Mark Sanford camp showing the Appalachian/Argentinian Trail trekker pulling into a small but significant lead over Elizabeth Colbert Busch in the 1st congressional district special election race that will conclude on May 7. Busch recently held a narrowly lead in the one public poll (by PPP), and in her own internal polling, and has so far outpaced Sanford in paid media advertising.
Folks also more reliably reports that Lindsey Graham has drawn a second 2014 primary challenger–Richard Cash, who narrowly lost a congressional nomination to Jeff Duncan in 2010. Already in the field is state senator Lee Bright, like Cash a hard-core social conservative who will call Graham a godless RINO. The divided opposition does not necessarily help Graham, since SC requires a majority for party nominations.
