Yep...this is leading more public figures to say vote on Impeachment and then delay sending the Articles to the Senate until McConnell commits to a fair (and real) trial. But the downside is that McConnell might find ways to sit on the issue until an opportune time. If he does that, they have the option of throwing their hands up, saying "We tried to do this the right way, but it's clear McConnell is abusing his power," and then instead issue a House censure and be done with it.
It's frustrating that Trump is getting away with high crimes, but the best way to defeat him is at the ballot box, which may or may not be possible. But from the looks of things, not just now but really all along, as it looks now, impeachment has always been a long shot because Senate Republicans have known that there isn't enough public support for it. And that's because there's not enough public loathing for Trump across the electorate.
It's up to American voters to preserve our political system and Democracy.
