The establishment wisdom that Carson could never be the nominee is so so wrong. This could easily happen: many Trump supporters vote for Carson in Iowa and he gets a plurality of the social conservative and anti-establishment vote. The media is unable to talk negatively about a black person, so nobody attacks him except for reasons other than "unelectable", which just makes him more attractive to most voters. Then he crushes New Hampshire if he engages door-to-door, townhall personable tactics. Then he crushes South Carolina by way of an aura of revolution and getting the social conservative vote as well as a uniquely increased turnout of black vote.

The stage is seriously ripe for Carson to win. The left has created this dynamic since they turn everything into race. A well-performing black person coming from the right would annihilate anything the left could muster.
