Btw neville the math is heavily stacked against trump. Many states, especially the early ones divide their delegates proportionaly so even if trump comes in first place he doesnt get all that states delegates.
Then of course there are the superdelegates many of whom are republican insiders who obviously will do anything they can to block trump.
Bottom line even if he wins a few priamaries/caucuses the odds of him getting enough delegates to actually win the nomination are negligible.
Sorry Hillary.
