There's a number of states that have already made it legal to overturn their own voter results as Trump wanted them to do in 2020. So even if Harris clearly wins both with the popular vote and Electoral College, she may still very well lose.
The same people that have forgotten all the hateful rhetoric and everything he's done will forget it yet again. Mind you, there's many in the very minorities he targets who are increasingly turning towards Trump, as if somehow voting for him will get them a pass when he tries to boot them out of the USA and the possibility of this doesn't matter to them because at least the grocery bill will go down a couple of bucks.
There will not be a civil war. America isn't 2/3 obese by accident. Fat people don't engage in Civil Wars. They don't engage in any wars. Heck, the military is running out of recruits because the usual pool has too many fat kids in it to pass the physical requirements to join.
Look at the January 6th crowd. One day, and the Civil WarII they've been talking about since Obama was over. Let that sink in. That was their Civil War. How many hours did that shindig last? And not so much as a march to this date to spew their anger because that would require getting off their gelatinous asses yet again. They learned their lesson. 6 hours jumping around the capital is kind of exhausting.
Even when they don't have to get up, they still can't hack it. Remember the Toronto Trucker Convoy Stoppage? Truckers were going to do the same thing in the US. And they tried. 2 weeks they collected to drive to Washington DC. They were going to stop traffic in the Capital, a la Toronto. And guess what, traffic stopped. With them in it. As it often does.
When these truckers arrived, they got stuck in traffic, basic everyday DC traffic jam. These guys thought it was going to be like a basic empty two-lane highway running through Wyoming or something. They had no concept what a city was, let alone the traffic. So within half an hour, as soon as they could get out of that traffic jam, all those truckers who were going to stop DC turned around and got the fhuck out. They didn't stop DC traffic, DC traffic stopped them. And that's it. The second and last chapter in American Revolution/Civil War II, ended with some truckers pissing their boots and turning when they saw what city traffic was like.
Nothing stops revolt like a full belly. Even the Romans knew this. A daily loaf of bread to those who needed it. Our Father indeed
