Going back to 2000, in recent memory anyway, both sides always claim the other side stole the election. George (Selected, not Elected) W. Bush knew this all too well.
I thought Trump would win, but then you could see the red flags going in. Parscale getting fired, facebook cutting him off, covid, and then the rapidly growing nonaffiliated voters. You know which demo had their enthusiasm drop for trump the most? White males.
If you want to talk about election interference, the biggest violators of that were facebook, mainstream media pushing nonstop negative coverage on purpose, the pharmaceuticals, and his own government agencies pumping out non stop propaganda. Time of all magazine outlined it.
The problem with things like the arizona audit, and pushing the narrative thaat trump somehow won in a landslide ignores real problems. It ignores techs influence, it ignores codifying shitty election practices like mail in ballots and extended counting deadlines. The next big hiccup I see is what the dems and republicans have been trialing in state and local elections the past few cycles, and that's the multiple national recount. Nikki Fried, who's running against DeSantis refused to concede when she lost the first count in Florida for Ag Commissioner in 2018. So she refused to concede and forced multiple recounts and the totals narrowed to the point she took a lead and then declared victory. Our law is wayy too loose with recounts and both parties know it. What happens is, they are actively pushed until the total flips. Gillum tried it with DeSantis in that election. Rick Scott won his recount against outgoing Senator Bill Nelson. Stacy Abrams tried it as well I believe. The overarching trend and strategy is to contest the results, where as it used to be an option of last resort. That's a problem.
