Mr. Trump has alienated his party and he isn’t running a competent campaign. Mrs. Clinton is the second most unpopular presidential nominee in history—after Mr. Trump. But rather than reassure voters and try to repair his image, the New Yorker has spent the last three weeks giving his critics more ammunition.
Even with more than 80 days left, Mr. Trump’s window for a turnaround is closing. The “Trump pivot” always seemed implausible given his lifelong instincts and habits, but Mr. Trump promised Republicans. “At some point I’ll be so presidential that you people will be so bored, and I’ll come back as a presidential person, and instead of 10,000 people I’ll have about 150 people and they’ll say, boy, he really looks presidential,” he said in April.
Those who sold Mr. Trump to GOP voters as the man who could defeat Hillary Clinton now face a moment of truth. Chris Christie, Newt Gingrich, Rudy Giuliani, Paul Manafort and the talk-radio right told Republicans their man could rise to the occasion.
If they can’t get Mr. Trump to change his act by Labor Day, the GOP will have no choice but to write off the nominee as hopeless and focus on salvaging the Senate and House and other down-ballot races. As for Mr. Trump, he needs to stop blaming everyone else and decide if he wants to behave like someone who wants to be President—or turn the nomination over to Mike Pence.
