Democrats these days are the party of disappointments. They’ve had three big ones. The first was President Trump’s election. Then came the success of Trump’s economic program. The third was Robert Mueller’s finding of no collusion between the Trump campaign and Russia in the 2016 campaign.

In each of these, Democrats were counting on the opposite to happen. With each disappointment, their despondency got worse, since the Democratic view of Trump is harsh and simple: He is evil. The better he does, the worse they feel.
