Republicans could lean on congressional procedure to defy the will of voters. But if they try that, the Senate has a clear way to fight back

Having lost his mail-in ballot case, Donald Trump will probably resort to ever more extreme ways to try to hold a Republican Congress in November’s elections.

His last-ditch effort to count Joe Biden out in 2020 was for Republicans to “investigate” states Biden narrowly won; proclaim fabricated allegations of “stolen elections” to be true; and then reassign those states’ electoral votes to Trump. I have previously described how that same playbook could be used to try to steal the midterms if a Democratic margin of victory in the House is relatively narrow.
