For the entire duration of the Trump presidency, prominent Democrats such as Hillary Clinton refused to accept the election results of 2016.
As a matter of fact, crooked Hillary still maintains the 2016 election was stolen.
As recently as October of 2020, Hillary said, "You don't win by 3 million votes and have all this other shenanigans and stuff going on and not come away with an idea like, 'Whoa, something's not right here.' That was a deep sense of unease."
Clinton's unsubstantiated claims of a stolen 2016 election haven't been met with condemnation from the left or the media, but only with validation. Democrats have defended these claims. After Trump's election, Clinton, the Democrat party, and the media promoted the "Russia collusion" lie — based on the fake Steele dossier that was paid for by the Clinton campaign and the DNC.
After the taxpayer-funded Mueller investigation found no evidence of "Russia collusion," which was a surprise only to Democrats, the Democrat party moved on to the Trump phone call with the Ukrainian president — "quid pro quo."
