I think you're right.  One more day of cratering and Pelosi will pull the plug.  The 2020 Dem candidates that are in the Senate (Booker, Sanders, Warren, Klobachar...there may be more but I'm just not that interested) are probably squealing like stuck pigs about having to leave the campaign trail for a trial with a predisposed outcome.  I imagine that they are hammering Schumer, who is pleading with Pelosi to make it all go away.
