> “There’s just a lot that I think will be revealed. History will discover,” the Democratic Party’s 2016 presidential nominee continued. “But 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.”

Hilary Clinton again in 2020 (which is the same election that Trump complains about, by the way) [2]:
> The 2016 Democratic presidential nominee predicted that among several scenarios, Republicans are going to try to “mess up absentee balloting” so that they could get a potentially narrow advantage in the Electoral College.
> “We've got to have a massive legal operation, I know the Biden campaign is working on that,” she said. “We have to have poll workers, and I urge people, who are able, to be a poll worker. We have to have our own teams of people to counter the force of intimidation that the Republicans and Trump are going to put outside polling places. This is a big organizational challenge, but at least we know more about what they're going to do.”

I also remember well the "Selected not elected" days after Bush v. Gore. That went on the entire time that Bush was president and went to sleep for a couple of terms when Obama won.
Just to be clear, I'm not making a judgement on who is right here. I think the truth is a lot more nuanced than "right or wrong." I;m just pointing out that we have a long history of politicians/parties questioning election results, but until now we've never had widespread attempts to silence it.
