She always does thing to be thinking two steps ahead somehow... I would welcome a Palin entry at that point.
There won’t be a late entry. In a brokered convention, the big GOP cheeses will do the brokering and they will pick Mitt Romney.
They aren’t going to pick anyone who hasn’t put any sweat into actually running. That includes, Jeb, Mitch, Chris, Sarah, you name it.
If that happened, nobody would ever bother running as a candidate again. It wouldn’t be worth it. The resentment would cause the chosen one to lose.
