One of the depressing aspects of the rise of authoritarian parties like Hungary’s Fidesz and Poland’s Law and Justice has been the fecklessness of their opposition — disunited, disorganized, unable to make an effective challenge even to unpopular autocrats as they consolidated their power.

Trumpism, however, faced determined, united, effective opposition from the beginning, which has been reflected both in mass marches and in Democratic electoral victories. In 2017 there were only 15 Democratic governors, compared with 35 Republicans; today the score is 24 to 26. And last year, of course, Democrats won a landslide victory in House elections, which is what made the impeachment hearing and vote possible.

Many of the new Democratic members of Congress are in Republican-leaning districts, and some observers expected a significant number to defect on Wednesday. Instead, the party held together almost completely. True, so did its opponents; but while Republicans sounded, well, deranged in their defense of Trump, Democrats came across as sober and serious, determined to do their constitutional duty even if it involved political risks.

Now, none of this necessarily means that democracy will survive. Even as they have been losing elections, Republicans have been consolidating control over the courts and other national institutions. Democratic leaders in Congress have been unexpectedly, even shockingly impressive; the Democratic presidential field less so.

And the unity of purpose we saw Wednesday may not hold next November. If Democrats nominate a progressive like Elizabeth Warren or Bernie Sanders, will wealthy Democrats decide that defending democracy is less important than keeping their taxes low? If the party nominates a moderate like Joe Biden, will some Sanders supporters express their frustration the same way they did in 2016, by staying home or voting for a third-party candidate? Given the stakes, I’d like to dismiss such concerns, but I can’t.

Add in the extent to which next year’s election will be rigged in Trump’s favor, both by voter suppression and by the skew introduced by the Electoral College — and the even greater skew created by a Senate map that gives small, mostly conservative states as much representation as liberal states with many times their population — and it’s all too possible that Trumpism will still triumph.

What we learned Wednesday, however, was that those who define America by its ideals, not the dominance of a particular ethnic group, won’t give up easily. The bad news is that our bad people are as bad as everyone else’s. The good news is that our good people seem unusually determined to do the right thing.
