That's at least encouraging. I've seen interviews with similar people in other states. Of course, who knows how representative they are? What seems clear is that there are quite a few of them.Exactly.
On the bright side, from purely anecdotal evidence of folks I know or am related to, I can count about a dozen South Carolinians who voted Trump that regret their vote and are voting Biden this time around. Again - purely anecdotal, but if everyone knows a few people like that, then that adds up. Gotta find hope where you can.
