I think you nailed Dr. Carson exactly. I was reading about some of the malpractice suits he has against him, leaving sponges in peoples heads, etc.
Lets be honest, if Carson wasn’t Black, we would never have heard of him. He is the least Presidential of all the candidates.
You might want to take a look at Senator Cruz’s behavior as a guide for your own. Shooting at the other horses in the race will not make your horse run faster.
Slandering the other candidates will not gain any votes for your choice. Make the case FOR you candidate if you want to win. Your current tactics will only piss off people who might otherwise consider voting FOR your choice.
