I don't know what's going on with Carson but it's disturbing. I understand the deep appeal he has with conservatives, specifically Evangelicals and those who herald the tokenism aspect of black republicans*. The thing that blows me away is his conduct. He has displayed a stunning level of ignorance on multiple occasions. Like Obama and Jeb Bush, he thinks while he talks...but unlike them he comes off as completely unversed on a vast majority of subjects. He's a doctor yet doesn't seem to understand how Medicare works for christs sake...
I wouldn't be stunned at all if we find out he's severely in debt due to a Ponzi scheme or something. Why he went from reserved surgeon to barnstorming speaker...I don't know, but debt seems like a possibility to me. He genuinely seems like a complete idiot on most non-medicine/surgery issues.
