Harper and Graham's internal had him above 50% to, so if Bright is actually struggling to keep above double digits, then he very well could beat out Cornyn's numbers. Unfortunately, hawkie is staying in Congress and if Ravenel does run, he likely won't make the kind of impact that Pressler could. This should encourage SC Dems to stay out of this race now and put their main focus on unseating Haley.
Haley's safe unless she has a scandal or flub between now and November. The statewide offices they need to concentrate on are Superintendent of Education and Lieutenant Governor since they are both open races. Maybe Comptroller General in case Richard Eckstrom's troubles prove more damaging than then currently appear to be. They also need to run more candidates in the downballot races. Sheheen's job this fall will not be to run for governor himself, but to be the Democratic standard bearer and hopefully help win the Dems some open seats even tho at best he's warming up for 2018.
