Yeah, this is obvious and a bit hypocritical. If it was voter fraud and Trump didn't really lose the election, then why are the people claiming that passing laws that make it harder for certain groups to vote? It's practically admitting that these legitimate voters are what won Biden the election.
Honestly, I think far more people disliked Trump than really wanted Biden and that is the winning margin - and that even fits into the MAGA narrative that Trump's opponents fomented irrational hatred of his administration.
That's really the basic thing though about the government. We have this perception that good government leads to good society, but obviously, if we have a bad society, then we're going to have a bad government. No one has ever voted themselves into a better government - it's about as successful as all the self-help mumbo jumbo the con men pull on their marks.
The government simply reflects the people it governs, and I don't really think that much of Trump but I don't really blame him for running the White House like an episode of the Apprentice. It's really his voters and supporters in the millions that give us the country we're living in now as well as the failure of his opponents to make better and more appealing arguments (yes, looking at you, Nancy Pelosi).
Honestly, it is going to have to be the next generation in 20 or 30 years that deals with all this. Most of us are just gonna have get too old, get too sick and die for anything to really change.
