I am well aware of that, let's see how many of his GOP colleagues join him. So far both GOP Senators (one of whom is running for prez), the GOP governor and GOP representative Mark Sanford have all declined opportunities to back him up, generally endorsing the current 'compromise' leaving the battle flag at the memorial. At this point he seems to be alone within SC GOP. Also GOP presidential candidates Cruz, Huckabee, and Santorum have all said they take no position, refusing to back him up and saying it is up to the state (as if a Presidential candidate can't take any position on something being decided within a state). The only one who has come close is Bush who noted that Florida stopped flying the flag.
Mitt Romney is standing out as a shining beacon at this point, but perhaps that is because he will never have to try to get votes in the South again.
FWIW, Jeb Bush also condemned it, and the state senator who's putting forth the bill said that several of his Republican colleagues offered to co-sponsor it.
