The way you can know for sure that politics is pure theater is by realizing that Trump never went after the 2020 election fraudsters. Those would have been EASY investigations, EASY prosecutions, EASY revelations to the American people, and it would have cleaned up elections from that point forward.
But no. Trump did nothing. Absolutely nothing. Why? Because it was never about honest elections. The powers that be WANT THE ELECTIONS TO BE RIGGABLE in every single case. That's why voting for one party or another, at the national level, is nothing but a humiliation ritual.
