This doesn’t change much. Trump is still bumping his ceiling with two thirds of Republicans voting for someone else. The question remains how the votes will coalesce as the field shrinks. A good showing by Kasich and Bush probably keeps them in the race a bit longer. This benefits Trump by keeping the opposition splintered, but i don’t see Christie, Carson, or Fiorina votes going to Trump as they drop out.
“Trump is still bumping his ceiling with two thirds of Republicans voting for someone else”
The other Repubs have 85%+ voting for someone else. What’s your point?
