Judging from this article and his website he hasn't developed any better ideas or worse ideas or any ideas at all. If you flat just want to get rid of Obamacare then say it. I can understand the reasoning behind wanting to do that. But don't say "we're gonna kill it by offering a better solution" and then offer nothing.
If he puts all his ideas out there without strong allies, the Democrats will skim a few off the top, cheapen them, distort them, implement them halfway and then blame Ben Carson.
He put himself out there. If he offers nothing then how can we take him seriously?
He has appeared on television a number of times, floating ideas. The problem with snap judgments is that they smack of the Pelosi whopper, “We have to pass it to find out what’s in it.” Give the man a chance to find some aupporters before you condemn him. He is a brilliant man, a moral man, and a voice for Americans. What’s really bothering you?
