Was this a great shock to you?
This bridge has been crossed.
In the political realm, we even have a self-proclaimed liberal lion that pretty much murdered a woman (left her in a submerged car to suffocate in a small air pocket) while he worked on his alibi. We have numerous presidents that have cheated on their wives while in the White House (some in wheel chairs, some in Camelot, some with cigars), so this is not really news anymore.
The cigar made the news, and that is when we were told such matters were none of our business.
But now....well, now that it's Trump you are SHOCKED at his infidelity.
This is a character flaw, but it's one we've gotten accustomed to accepting thanks to historical occupants of the office. The bar has been sufficiently lowered. Heck, I bet one day an evil woman that worked to discredit and destroy her husband's victims will become president...just not yet, thankfully.
