We have similar opinions of McConnell. Agree with your assessment.
McConnell is part of the DC Swamp problem, no doubt. Indeed, I STILL am not 100% sure why he put the kabosh on Garland...it certainly wasn't love of rules, it wasn't that he secretly hoped Trump would win, and maybe he really did want Hillary to win. Maybe Obama did something that REALLY got to him and he took this opportunity as payback.
RINOs don't like to appear partisan....they work for the Uniparty. That's why, for me, for McConnell take all that abuse in public (and probably in private) AND to go down in SCOTUS history as a figure with a cloud over his head over this nomination saga is VERY uncharacteristic.
Thus, I praise McConnell (R-Swamp) in this limited instance the same way McCain (R-Keating Five) is rightly trashed for his legislative service but is positively acknowledged for his war service.
