They did break with Trump. They did certify the election.
if your bar for “Republicans demonstrating their desire to overthrow democracy” cannot realistically be met until they actually do that then i think your bar is bad and hopelessly naive, because at that point neither you nor i will live in a democracy and the bar will cease to be relevant.
but even entertaining this bar for some reason: please remind me how many of these people then supported actually prosecuting Trump for extremely unambiguously committing several crimes, including attempting to overthrow the election and inciting a mob that threatened to kill all of Congress.[^1] and let’s then take stock of how many Republicans who feigned shock and gall at the event subsequently act like all that never happened, openly apologize for it, or state they would refuse to hold Trump accountable for/actively support similar criminal actions in 2024. to say nothing of how many state Republican parties (Wisconsin, North Carolina, Michigan, Arizona), even pre-Trump, had fallen completely into believing that land should vote and that the only elections which count are ones they win. or how any initiative to ban gerrymandering or to abolish the undemocratic Electoral College is Democratic-led, because Republicans benefit from their continuation?
[^1]: 17 of 261, for anyone wondering. only six are still in Congress in large part because Republicans and the Republican base have purged them from the party
