Donald Trump is due in New Hampshire this evening. He will attract a large crowd. The crowds, the media coverage, and the polls have led him and some pundits to believe that he will win the 2016 Republican presidential nomination.That is an insult to the intelligence of Republican voters. Beginning right here in New Hampshire on Feb. 9, a great majority of them will disabuse him of that notion.Much of the news media are lavishly covering Trump, not just because he’s good for ratings, but because he’s good for Hillary Clinton. They very much want Trump to be the Republican nominee so that Ms. Hillary can move back into the White House.
