To be fair, we're not getting out of this without civil unrest on one side or the other. Too many people on the republican side of the fence feel like they've been cheated, they're going to be staging demonstrations and agitating the other side into violence, and if Trump wins groups like antifa and BLM are going to go into overdrive.
My personal theory is that fraud was committed in large enough numbers to change the result of the race, but most of it was independent of each other. There -might- be an overreaching scheme in play, but I think a lot of major cities just had ballot stuffing. The lack of straight ticket voting in the disputed states only compared to the rest of the US is suspect, so is the exceptionally high voter turnouts for their elections in these cities. And to top it all off, these states only flipped after pausing their count and reporting results at 4 AM again, which is highly suspicious.
I don't think the Trump team can prove enough fraud in a wide enough spread in a short enough amount of time to take the election. I think it's possible Arizona might flip red and Georgia too, but getting anything done in Pennsylvania with a hostile regime is likely a no-go. Michigan and Wisconsin are also fairly unlikely from what I've read.
If this is the case, the next step will be to continue to hammer in the message that the election was rigged to republican voters and make it a hot topic for 2022. Anyone who didn't support Trump during this needs to lose their seat for it as they've been outed as caring more about the smooth operation of Washington than probing for fraud. Most of those who don't support Trump never liked him and want to go back to the old republican platform and see this as an opportunity to do so (Fraud will be harder to commit without mail-in voting next time, so they're less worried about correcting it when it was a one-time occurrence from their standpoint.).
