John Fund‘s latest National Review Online column explains why President Trump’s most vituperative critics might be his best asset.

The good news for Democrats is that the apathy of many of their voters — which contributed to Hillary Clinton’s losing in November — is gone now that Donald Trump is president.

“We have never in living memory seen an electorate as fired up and angry and engaged as they are right now, Ben Wikler, Washington director of the left-wing group Moveon.org, told RealClearPolitics.

The bad news for Democrats is that the fires of protest could burn so brightly that they alienate moderate voters and threaten any Democrats who decline to throw gasoline on the fires.

The anger of the liberal base is such that “a firestorm of criticism . . . awaits [Democratic lawmakers] when they don’t stand up to Trump,” Wikler says. As for primary challenges for Democrats who won’t confront Trump at every turn: “Everything is on the table.”

It certainly has been when it comes to the ceaseless efforts to delegitimize Trump. As soon as the election was over, state recounts were mounted, with the approval of Hillary Clinton’s campaign, angry demands were made that members of the Electoral College go against the results of their state votes and dump Trump, and wild charges were hurled that Russian hacking swung the election. FBI chief James Comey, an Obama appointee, was accused of tilting the election against Clinton, and blue-collar voters in the Midwest were smeared as “racists” who were easily manipulated by Trump.

Of course, missing in the progressive reaction to Trump’s victory was anything more than cursory mention of why the Left, during Obama’s eight years, had failed to fulfill promises of “hope and change,” address rising income inequality and middle-class stagnation, or win the respect of either America’s friends or adversaries.
