History shows since the 1970s less than a third of republicans and less than half of democrats who have won here have gone on to win the party nomination. Donald trump holds a lead over ted cruz. Political analysts come down to turnout. Turnout will tell us something whether he has changed the electorate thats the prospect. Can he bring out new voters who have not voted before. Reporter turnout will be key for Bernie Sanders who is in a dead heat with hillary clinton. Bernie sanders is counting on young voters to come out and people who never caucused before and never had an attachment to the Democratic Party to come out and vote for him. Reporter clinton is 3 points ahead of sander with Martin Omalley far behind. Omalley said he expects to do the unexpected. He thinks he will perform better than the poll say. Even though he is the distant third he wont be dropping out. Experts say the likes of Rick Santorum or Mike Huckabee may call it quits if they dont perform up to expectations ton
