You have made myriad statements which can only be made honestly in the presence of a belief that such a theft were actually a plausible occurrence.
This is done through the form of attaching contingencies of question around well established facts.
In fact, we have a thread here, the whole thing, something you started, crowing about "Dems should take a lesson from Republicans", when the lesson at the head of the OP is "snitches get stitches".
There is no question that Trump has committed myriad crimes.
Your refusal to look at any of them and say "yeah he did that" is telling.
Trump actually winning is indeed a plausible occurrence or there would not be so many people that believe it. I've never said that I think the election was stolen though. I have said that our election system is deeply flawed and still continue to believe that however.
I view Trumps election in exactly the same way I view UFO's. I've never seen one myself but that does not mean aliens have never visited it just means I do not know. Nothing more or less than that.
My old college roommate swears up and down that he was abducted by aliens. He even used his artistic talent to illustrate his "experience," and has had his work published in various UFO books. He only "remembered" his abductions after a traumatic event in his life, and one of them occurred while we were still living together and he and his girlfriend did a lot of LSD one summer. Hmm...
Now, is it plausible that Trump won the 2020 election? No. The 2020 Presidential election was - oddly enough due to Trump's preemptive claims of fraud - easily the most carefully scrutinized Presidential election in US history. The votes in every single "swing" state (where there was a narrow margin of victory for Biden) were recounted, audited, and examined by all parties involved. Here in Arizona - a very close race - there was (deep breath) observers from both parties personally watching over the counting of the votes, a live-stream of said counting so that the public could see it in real time, a recount, a forensic audit, and an independent audit organized, paid for, and run by people who believed wholeheartedly that there was "voter fraud" and that Trump actually won.
They actually found that Biden won by an even larger margin than the official results.
The fact that "so many people believe" Trump won does not make it any more plausible. A whole lot of people around the world believed very sincerely that Jesus was coming back (checks notes)
over 22 years ago to usher in a new Kingdom 'O God on Earth (or rapture, or whatever). I'd guess that out of the world's 2 billion Christians, a lot of them (more than the entire population of the US, probably) think that prediction was just off by a bit, and any second now Jesus will be coming back. Yep. Any second now...
A whole lot of people buy lottery tickets hoping to win a life-changing amount of money. According to the Tax Policy Center, the US lottery industry made
$29 billion in 2019. Is actually winning the lottery indeed a plausible occurrence simply because a lot of people play? No. Winning the lottery, being abducted by aliens, Jesus coming back, and Trump actually winning the 2020 election are all not plausible.
Saying "well I don't believe it, but a lot of people do" does not change that fact.
