What could be more compelling for a removal than a SC justice who didn’t follow the law? That would follow the example of several Congress critters.
I believe you’re extrapolating from the current exigencies and not those changed circumstances that may exist in a few months from now.
The future definition of an impeachment and removal will hopefully have far less to do with corrupt protection of those affiliated with one’s party and more to do with an unbiased assessment of whether one has truly merited removal.
I would be delighted to see more senators who would do their duty, but where are 67 coming from? If Walker wins it's 50-50 in 2023, with Murk and Romney having voted to convict and remove Trump.
