The truth is, they don't really believe that. They're just playing politics. Or they are so brainwashed they don't even know they are doing it.
What's funny is there are a million pieces of evidence that suggest Bush stole 2000. And probably Ohio in 2004. Lots of evidence. If any of those things happened to Trump, they would be out of their minds. But then Trump said a bunch of things that didn't happen to him happened and they swallowed it all. And when asked why Rudy and Fox owe Dominion 700 million dollars for lying about them, they just ignore that. All the thrown out cases. It's OBVIOUS Trump tried to lie and steal 2020.
And a lot of the things Trump said we did to steal 2020, Bush did in 2020. Don't forget that Trump was a Democrat back then. No question about it he believes Bush stole 2000 too. No doubt. It's most likely why Trump thought he could get away with it.
“When she first got in and was named speaker, I met her. And I’m very impressed by her. I think she’s a very impressive person. I like her a lot. But I was surprised that she didn’t do more in terms of Bush and going after Bush. It was almost – it just seemed like she was going to really look to impeach Bush and get him out of office, which personally I think would’ve been a wonderful thing,” Trump told Blitzer in the interview.
So Trump thought he could get away with all his petty crimes. If Bush could get away with lying us into war and not get impeached, why can't he get away with those calls to Georgia and Ukraine? And starting an insurrection? And stealing an election. Bush got away with all of it and most Americans don't even realize 2000 and 2004 were stolen.
