But I think our respective focuses (or is it "foci"?) are different: in my view, this trial is about Donald Trump, and no one else. And the polling is not good for him. IMHO, it's going to get worse: https://www.monmouth.edu/polling-institute/reports/monmouthpoll_US_012521/
I am assuming damning evidence is going to be brought out trial, unlike the 2020 trial. I think it is inconceivable that any of that evidence could benefit Trump. Those poll numbers are likely going to increase, not decrease, in favor of conviction and prohibition on holding any other federal office.
At best, the Rethugs are simply going to argue that it "unconstitutional" to convict a former President, which, conveniently, bypasses the Senate's hearing the evidence. That's already done and dusted, with that view losing 55-45. The more damning the evidence is, the harder is it for some (but not all) Senators to vote effectively in favor of Trump.
Of course, I am assuming there will be damning evidence. If not, then my thoughts don't apply. As far as I can tell, the minimum number of votes we will have to convict is 55. In other words, the Ds need "only" 12 more votes to get to 67. If no major evidence comes out, Trump will be acquitted.
I cannot fathom how any Democratic Senator could view going lightly on Trump's actions in relation to the insurrection as helping the Presidency. Indeed, it is precisely BECAUSE they believe Trump harmed the Presidency and the United States that they impeached him and now are putting him on trial.
Going after others in Congress is a separate issue for a later day. Right now, the issue that is front and center are the acts and omissions of that monster known as Donald John Trump.
