Carson can have Iowa. Trump will still win NH. And all the others will drop out like flies.
If Carson were ever to stop the Trump campaign, the puppet masters would destroy Dr. Carson in no time and the elite will try to force-feed us Jeb, or someone equally awful.
Somebody should tell the real Dr. Carson supporters they're being played. Meanwhile, it'll be fun to see how Trump plays this one out.
From what I hear people say Trump can win South Carolina and only one Republican has ever won our primary and NOT become the nominee. That was Newt Gingrich and Romney came in second in 2012.
