I would have liked them to push on how Trump and a bunch of other republicans are not eligible for office because of the insurrection. Go for blood. Refuse to acknowledge that that these people hold office.
No person shall be a Senator or Representative in Congress, or elector of President and Vice-President, or hold any office, civil or military, under the United States, or under any State, who, having previously taken an oath, as a member of Congress, or as an officer of the United States, or as a member of any State legislature, or as an executive or judicial officer of any State, to support the Constitution of the United States, shall have engaged in insurrection or rebellion against the same, or given aid or comfort to the enemies thereof. But Congress may by a vote of two-thirds of each House, remove such disability.
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.
