That's probably not a wise tactic.
It is possible the election was stolen, but frankly I don't think it's likely. I don't find it plausible that a massive conspiracy to swing the vote in multiple states, involving numerous precincts, counting stations, etc could have been pulled off without a hint. There should be leaks from the inside. Cell phone recordings of the planning, copies of the emails used to coordinate, etc, and there haven't been.
That doesn't excuse the outright refusal to do a proper audit and ensure that everything was done properly, or the hypocrisy on the part of the media and democratic establishment that insisted 2016 was stolen for years and then did an about face the second it was convenient for them, but it does mean that running around claiming the election was stolen has some issues, and since the 6th, crippling issues. As of right now, that narrative is going to be forever associated with a series of riots that got people killed pointlessly (and gave the dems a new weapon to use against the rest of us....thanks). Unless you have absolutely irrefutable, uncontroverted, crystal clear slam dunk evidence (and you don't), pushing that narrative is not going to work out, because it's going to alienate the people you need to appeal to in order to win next time. And before you go "but they'll just steal it again", there are three issues with that (well, four, but "they didn't steal it the first time" isn't really an acceptable answer to you).
First off, we have 4 years to lay the groundwork now. Get better security in place, start volunteering to work the polls ourselves and get like minded people to do so elsewhere, etc. They can't tamper with a system unless they control it.
Second, the "but muh global pandemic" stuff isn't going to fly next time, no more cheeky moves with mass mail in ballots and the like, those were sold as temporary measures and we have to hold them to that.
And third and most importantly, any operation like this has limits. They can only tip the scales so far, in so many places, if we build a large enough supporter base it doesn't matter how much they cheat in a few spaces if they're drowned out elsewhere. That's what we have to do going forward. Rebuild the party, figure out a game plan and a massage, and take the government back.
This is definitely the biggest issue we have right now. Those idiots on the 6th gave the democrats the excuse and the platform they needed, and it's going to be a tricky thing to stop, but far from impossible.
