A guy who can't get 50% of Republican Primary voters support isn't going to win any landslide election.
Yes he will. He'll get the delegates he needs. That 50 percent figure will be totally irrelevant in the general election. Hillary probably won't carry her home state of New York.
Trump is going to redraw the Electoral College Map. Hillary has already lost Ohio and Pennsylvania with her anti-fracking remarks. And you KNOW Trump is going to hammer that point throughout the entire campaign.
She'll be conceding within the first hour after the polls close.
