Up until people wearing MAGA hats showed up at the capitol, the left had been really tolerate of egregious acts committed there. Up until some people wearing MAGA hats got a little unruly, the left didn't care about "riots". Until they saw the police as protectors against the evil MAGA hats they didn't care about police. Until all of this they didn't want to use the national guard, now DC is swarming with them. I'm not even sure they cared about "terrorists" until they decided to call the people at the capitol that.
This irrational fear can be used to our advantage. When we wanted the national guard in DC they resisted it, because it was BLM burning the town down. If it had been MAGA people though, we now know they'd have put that call in right away.
We know there are people that ordered ballots from China. We know that voting machines can be hacked. We know that they put unsecured ballot boxes in the street. We know they didn't check the signatures on the ballots. We know that they pulled ballots out from underneath tables and shipped them across state lines. We know that people born in 1900 voted over and over. We know that people who voted didn't even have to be on the voter rolls, etc, etc, etc...
Now, I ask you how would they react if they thought MAGA people were doing those things?
The FBI will actually take the time to follow their oath, investigate, and indict anyone on the right who would do anything to affect an election. That's the difference. The left has no fear except the stupid woman who was arrested in the one state left with balls in this country. TEXAS.
So what would be bad about massive voter fraud, right or left being uncovered? All you would want them to do is up their security, doesn't matter why.
