Good questions, I have to get to work so this will be short but here goes: At its worst election fraud is treason, the only difference between a banana republic and a working society is honest elections. When the side doing the crime owns both the media and the law it can appear that a lack of charges and fake investigations proved no fraud happened. The evidence is real and so was the fraud, faked investigations (a few low hanging fruit did go to jail) and media cover stories all real. There were experts that proved more voters than possible, ballot harvesting, ballots changed and faked human checks (things like three seconds to check each, if no breaks and a 24hr schedule were used. Before we play the evidence game, only accepting it from sources you approve of remember who owns the media, the fact that you do not know where to find the evidence shows their power over media, and over your mind. 6 corporations have almost 100% control over American media. Which source you watch, read or hear doesn't matter. If you want, you can watch the rumble videos that show a dozen stations at a time all repeating the same story, word for word, all use Reuters or AP. Funny but sad no discussion just sponsors approved rhetoric.
You other points work the same way, no matter how many people actually voted, only positive stores on the Bidens run (there are a fe exceptions but nothing major. A few would be media stars (independent) have made funny but sad tiktok videos asking randoms about many Biden family scandals and most have never heard of them, again media control is working. Fake polls, only running positive stories and tossing, censoring, canceling and now jailing of dissenters all proof positive the old United States is dead.
