Is there anyone here who doesn't believe that the decision to impeach or not has already been made? Do you honestly believe that anyone in that hearing will change their mind?
Who can say for certain? Considering the composition of the Senate and the extreme unlikelihood that they'll vote to convict, it does appear to be a waste of time.
I doubt it will change many people's minds. Those who were against Trump already will still be against him, and those who were for him will still be for him.
What I've noticed these past few years is that a lot of people have made Trump himself into the issue, but there's been very little discussion or attention paid to the issues facing the country as a whole. This tells me that their argument with Trump is not really political.
That is, those who oppose Trump ostensibly
agree with his politics, for the most part. If they didn't, then they would say so, but in essence, all they're really talking about is what he did wrong and allegations of criminality (along with being offensive and obnoxious). There has been very little attention or any meaningful public discussion about actual political or philosophical differences throughout all this.
I don't think these proceedings are a "charade," but it just reinforces the perception that Democrats are afraid to take any real political stance. That's their main problem, but instead of looking inward, they've fixated on Trump as some kind of "Anti-Christ," which may very well be true, but it plays right into the hands of those who think that Trump is the Second Coming.
