As Democrats bask in electoral success the Czech Republic, Slovakia, Poland and Hungary offer a cautionary tale

In the afterglow of electoral triumph, hope springs renewed for Democrats confined to the frustrating impotence of political opposition.

Boosted by last week’s electoral wins in New York City, Virginia, New Jersey and elsewhere, as well as California’s affirmation of Proposition 50 allowing for congressional redistricting, party members suddenly feel able to dream that future elections may herald an escape route from the Donald Trump era.

Yet the experiences of other countries that have grappled with the rise of rightwing authoritarian or populist movements provide a cautionary antidote to such optimism.

It suggests that even the rosiest Democratic scenario – one that would see the party retake control of (at least) the House of Representatives in next year’s midterms, and win the White House in 2028 – might not be enough to permanently break the feverish intensity of Trump’s Maga movement.
