@LiberalLibrarian: Nikki Haley and Tim Scott as dangerous to, well, really any Democrat, not just Biden? Whaaaaat?
I'm in SC, and Nikki Haley wasn't a popular governor, even with Republicans, and Tim Scott only got the job because he was the R that made it to the General Election. He's not even terribly popular here, and word is here, in the press and publicly, that if anyone in the party remotely qualified ponies up to primary against him, he's hot a 50/50 shot at best of keeping his job.
