If you think the Donald can beat Hillary just by tweeting a few insults, you may want to check the 50+ most recent polls concerning a potential match up with Hillary. The most recent show Hillary up by 12%. Trump won just two of those polls, neither by more than the margin of error, and ‘none’ in 2016.
Remember, IF he wins his home state NY, as expected by the margin expected, it will be the ‘first’ time he has broken the 50% mark in any state, and that’s just of the Republican party, with some Dem crossover in open primaries. ...think Electoral College.
Trump hasn’t even started on Hillary yet, and she’s struggling to beat an old socialist, so I don’t see too much trouble with Trump beating her. Heck, all he has to do is brand her with the proper nickname and she would dropped 10 points in the polls. It’s worked for him against every other candidate he’s faced so far.
