Then they should have rioted against that. But that isn't the case. They are rioting against the election results specifically. I know that our political system is corrupt. The issue is, Trump is endorsing it. He wants it so his supporters want it. Trump doesn't get his way, his fans get angry. The message of the rioters was very clear: "Stop the steal." Not "Stop the corrupt politicians in office and excessive term limits!" That's usually a democrat talking point.
