However, that doesn't necessarily mean the impeachment was a mistake, for a couple of reasons:
- It may have caused Trump supporters to rally around the racist, but it also may help energize Democrats as well. (Many democrats also saw an increase in fundraising during the impeachment proceedings)
- Its hard to know how the alternative might have gone. Ok, so Trump's approval ratings ticked up by a little bit. If they didn't impeach, it may still have gone up. Or it may have stayed the same.
- It may have a secondary benefit on some of the congressional races. Senators like Collins (who was already dealing with low approval ratings) now has the stigma of her "Trump learned a lesson. He didn't? My Mistake". This may play a part in her 2020 senate race.
