https://www.politico.com/news/2021/01/13/trump-approval-rating-poll-458602A new POLITICO/Morning Consult poll pegs Trump’s approval at just 34 percent, the lowest in four years of tracking opinions of the president’s job performance.
Not that much off the ~40% he's usually at, is it?
Three in four self-identified GOP voters still approve of the job Trump is doing as president — 75 percent — but that is down from 83 percent in the final POLITICO/Morning Consult poll of 2020, conducted in December.
There you go. His base is still there and it's still holding the GOP hostage. This is basically a death sentence (hopefully not literally; just losing the primaries) for the political career of almost any GOP senator who considers voting to convict Trump in the impeachment trial.
I would not trust the polling of approval ratings. The polls were far off in the 2020 election, and I have no reason to believe their accuracy has since improved.
Trump is not going to be tried while he is in office, and if he remains banned on social media, his grip on his base is going to deteriorate. There are plenty of Republican Senators who will not have to win a primary for 4-6 years, by the time which Trump will long be forgotten.
