Tom raises an interesting question.
Other than crawling from abject poverty, finding a massive education, and rising to the top of a "cream of the crop" medical profession to end up a highly skilled and world reknowned pediatric neurosurgeon, he's got nothing. Pit him against a guy who has never held a job in his life until now, has never run anything, but somehow is pretty wealthy, and has really done nothing but write a few books about himself and his ego, and is now screwing the pooch at the only job he has ever held, how could Carson possibly be considered a legitimate candidate.
He has actually accomplished a LIFE, so that would disqualify him from taking an elected position as a worthless POS.
