To begin to repair the damage done, they need to see not that their way almost succeeded, if only one or two states had broken differently. They must absorb the painful reality that their way cannot, will not, ever work again.
So when it's over, Trumpkins, remember: You're not purging us. We're purging you.
No more hate and reckless group blame. No more fact-free fearmongering. No more feeding the obese ego of a man who's transparently unfit for the job.
And after the party gets this philosophical poison out of its system, it needs to re-professionalize the way it wins elections. You'll see at the end of this race dozens of articles on how Hillary Clinton's team took the amazing data science and voter contact architecture created by Obama and enhanced it.
This wasn't rocket science; it's basic, professional campaigning. While Donald Trump was retweeting "White Genocide 1488 Ovenmaster," Clinton's campaign was building data files and contacting swing voters. While Trump was tweeting about "Crooked Hillary," she was having precisely targeted television ads aimed at swing voters in the suburbs of key cities in battleground states appearing at just the right moments. While Trump was depending on red hats and WWE rallies, her people have been going door-to-door by the thousands, knocking, talking, winning hearts and winning votes.
I know Trump fans think of professionalized campaigning like this: "We don't need you fancy smart people with experience and your campaign discipline and your writers and polls and your computers and your TV ads. All we need are hats and Trump's Twitter account. Hold muh beer while I build a wall and make Mexico pay for it."
I feel his pain and truly hope the GOP becomes a real party again some day. I know the Democrats need a yang to their yin.
