Big Magilla, can those senate rules (the ones preventing Senate business during an impeachment trial) be changed unilaterally (aka, by the majority?). If they can, they they should have been.
Beyond that, it's not about changing the 43 minds that's at stake. It's about permanently yoking, in every aspect, the Republicans to Trump's actions. Cassidy got censured by the Louisiana GOP for his vote. The GOP at the state level is a full Q-anon party. It's about telling the people who are going to be marginalized and damaged by the GOP at the state level that the Democrats aren't taking their votes for granted and will use every power they've got to protect them and their citizens. Listening to Sinema about the filibuster, for example, is completely enraging. And the people who are working so hard to get Democrats in power are the ones that will be first in the firing line against any GOP chicanery. Do the Democrats care that they are up against a fully counter-majoritarian, anti-democratic party? Or do they care more about keeping the senate rules in place.
Trump is going to run for the nomination again, and he's absolutely going to get it. Someone posted that failed coups without consequences turn into practice runs.
I'm more on Sabin's side on this one. I'm not American so the affect it has on me is different, admittedly, but the fact is the world's best hope to get the USA on a more hopeful path is with the Democrats. That's bleak.
