Tim Scott is reportedly the frontrunner to replace Demint. Scott has fits of conservatism but no where close to Demint. He'll do as a fill in. Bad news is that makes 2014 a year in which both senate seats up for grab, which I thought wasn't supposed to happen.
The fact that Demint is bailing out early makes me wonder about what will be happening in the senate. Reid is already preping the battlefield for use of the nuclear option (eliminating the 60 vote hurdle to conduct business). . . . . the very same nuclear option spinelessrepublicans discussed and dismissed in years past. The only factor differentiating the house from the senate is 60 vote requirement. Direct election of senators was a bad, bad mistake and now we will see why.
