Should ‘Never Trump’ people get over it?

Washington state's Republican Party just defied the stampede toward "unity." Meeting over the weekend, they awarded 40 of the state's 41 delegates to Ted Cruz. Washington's Republicans have refused to be sheep.
The past few days have featured hectoring demands of Never Trump people to "get over it." These have come not just from the more bullying precincts of Trump fandom, as in "Get on the Trump train or get run over," but also from party regulars and officeholders suggesting that failure to endorse Donald Trump now is a kind of stubborn self-indulgence. "While you sit out, Hillary gets elected," huffed one of my critics, for example.
