I think a ripple effect of the multiple Trump-peachments is the watering down of pubic perception of impeachment. Not sure if it was intentional or not, but by beating the dead horse, it created a feeling among the general public of "big whoop, another day, another impeachment, doesn't really matter". The failure to remove Lying Bill fed into that perception also, methinks.
Which puts me in the camp of: accountability comes by voting Sleepy Joe and as many donkeys out of office this year and 2024, and getting Republicans with spines into office with the understanding they get their shoulders to the wheel or they will be unemployed just as quickly.
