The aquittal was always a foregone conclusion - Republicans who have their eye on the next elections are never going to put realism anc concience above party politics.
I think everyone knew that this would never fly, and I suggest that the only reason the impeachment process was started was so that the 'twice impeached' label will attach itself to Trump should he try and run again.
Of course he was not found guilty, but that's still a label that will seriously dent his chances in 2024 if he tries again.
Trump wll see it as a vindication, and that it adds even more fuel to his martyr's pile, but hopefully reality will continue to be at least an influence in American politics.
