Palin, YESSSS..!!!!
This is how you build a unified party. Each of these folks have very passionate supporters....but their appeal is narrow. This includes Carson. You float a list to Ben, and tell him he can float a few names to the press. The supporters of X begin to soften to Trump.
The only downside risk is if some of the folks listed play the @$$hole, or Carson tells enough tall tales that his biggest asset, absolute honesty, gets shot to hell. Trump is very fortunate to have Ben as a spokesperson.
My mother (84) and my son in college (20) have only come around for Trump due to the support he gets from Carson. It is interesting to watch.
