^^^^^ Did you notice his approval numbers went up when the last impeachment proposal came up.
No it didn't. The day of the formal announcement was his highest approval rating all year, but that means people had been asked the question before the announcement. It has been drifting down ever since.
Really it hasn't moved at all. It is between 41 and 43 percent (other than the occasional outlier poll) and has been there all year. It doesn't move much. Will this change it? Who knows. I doubt it.
