I can't predict how things will shake out...but, realistically, it's fair to hold people in congress (as well as mayors, governors, presidents) to a higher standard than what a comedian makes jokes about in their acts (as long as they are not committing any of the egregious acts in real life).
Whether someone finds a certain type of joke funny, insensitive, offensive, hateful, etc, is all on the person....but we can't allow people in roles of leadership, people we elect to represent us, to just do shitty things with no consequence.
