I find it disturbing that many are still supporting him, excusing, rationalising, and justifying his comments. They broadly fit into these categories:
-it was such a long time ago
-other people have done worse things
-every guy does it
-it's not that bad
-the media are out to get him
-etc...
Bottom line is that this is a man who is not fit to be president in any way.
I gained some respect for some of the Republicans who never endorsed him from the beginning. They saw how flawed he was from the beginning. Fiorina, Jeb Bush, John Kasich, and others to mention a few.
Those who are now condemning him and disowning him are doing so out of political convenience. After all that Trump has said and done, this last one isn't really the straw that broke the camel's back. That straw should have been a long, long time ago.
For me, I actually liked Trump when I first learned about him. I admired him for his brashness, independence, and willingness to say what was on his mind, even though it was not politically correct. I found the feuds with Rosie kind of funny, and when he said he only called Rosie fat, ugly, and a pig, I actually found it kind of funny.
However, after the very first controversy (him calling Mexicans rapists), I was done with him. From then on, it seems like every day he has said something to offend people and reveal his ugliness.
