Even among people who like trump, there are plenty of people who know that he lost the election.
Even if Biden cheated (and I’m not saying he did), people who cheat to win elections are called the winner of the election. Laws tend to fine campaigns for cheating rather than changing the outcome of the election.
As an example where a campaign was fined for malfeasance during a campaign, the Clinton campaign was fine for misbehavior in the 2016 election related to the steele dossier politico.com/…/dnc-clinton-campaign-fine-dossier-…
However, although that example was of a losing campaign, up in my home country of Soviet canuckistan, several election cycles ago the conservative Stephen Harper government was fined for election fraud, and that’s all that happened. They were officially in charge and they stayed that way until the election of Justin Trudeau in 2015.
Typically, lawmakers want election issues to be dealt with by the electorate, they’re extremely extremely wary about stepping in and changing elections on their own.
While we’re on the topic though, I would like to remind everybody that it is extremely typical for the losing side of an election to claim that the other side cheated. In 2000, there were plenty of people pointing out fuckiness in the supreme Court decision that ended George W. Bush the election, and in 2004 election machines were singled out as a potential method of cheating by the Democrats when John Kerry lost the presidential election, and in 2016 there were lots of cries saying that there was election interference that led to the election of Donald Trump.
