I feel like that is one of the bigger cultural shifts, particularly in politics, that has happened over the last decade. It used to be that the mere appearance of impropriety was enough to kill a political career. Now it seems like not only is the appearance irrelevant, actual evidence of impropriety is losing its effect too.
Yes, and in more and more cases, actual, overt, and open impropriety (not just evidence of it) serves to improve a politician's standing with the public. Nothing is out of bounds anymore. It doesn't matter what a politician does, how terrible it is: If they are doing it For The Team, then that team supports it.
