Calling him a traitor on the campaign trail isn't the same as actually enforcing the law, at gunpoint if need be. Laws don't matter if they're not enforced. They should be physically removing the republicans from office.
I want republicans dead. That's not really practical but that's what I want. Every republican up against the wall. The big players can get a guillotine.
More practically? Probably impeachment proceedings, noncompliance, fillibuster, malicious compliance, push hard to the left and sell people on a future that's not climate collapse and wage slavery.
