I have maintained for a long time that the legislative calendar in the House is fixed and set. The last day to hold a full floor vote in the House is December 12th. That isn't a made up date. I don't know if that can just be arbitrarily changed or not. Given the holidays and politicians propensity to want to leave DC, I would think not.
There is nothing "artificial" about my timeline. The legislative calendar IS the legislative calendar.
If they don't have a full House vote by December 12th (eight business days from now), then that pushes this all the way into January. I know you say you don't care about that, but I know six democrats running for President who do care about that. And I suspect that they would rather be out campaigning for their party nomination rather than stuck in the Senate during an impeachment trial.
But, hey if you think they won't care, who can question your judgement? When have you ever been wrong before?
