Access Hollywood? I did say, dissing women;
I don't outsource to David Letterman;
I did mention "dissing Mexicans" so that too is covered.
You are correct though that I missed the McCain diss. It's a lot to remember off the top of my head. So many disses, so little time.
So here's a revised list. I've incorporated McCain and added a few more, including another mention of Access Hollywood from another angle.
I scored... running businesses into the ground, dissing Indians, destroying the USFL, tanking an airline, utterly failing at ill-advised casinos, selling vitamins based on customers sending in pee samples (prophetic), contriving fake press agents, then admitting to it in court, then denying what he admitted to in court (which makes it perjury), dissing his own spouses, dissing his own beauty contestants, walking in on those (teenage) contestants while they're dressing, unannounced, dissing his own daughter and using her for salacious soft-porn shots, dissing Mexicans, dissing Muslims, dissing the Constitution, dissing women, marking rent applications with a "C" for "colored", getting busted for that, telling the FBI investigator "come on Elyse, you don't want to live with them either", claiming to have come out of it clean when he didn't, then doing it AGAIN, dissing black people elsewhere ("black guys counting my money, I hate it"), defrauding gullible saps with a fraud university, dissing the judge in that suit claiming he'd never settle and then settling to the tune of 25 million, inventing an entire new country for his father to have been born in, declaring "would" means "wouldn't", claiming Revolutionary War pilots took over the airports (perhaps that's where the Rump Spittle Shuttle went down), saluting a North Korean officer, pledging to release his taxes and then failing to do so, embezzling from his own "charity", inventing his own fake Time Magazine cover, dissing a POW for being a POW, skirting Vietnam by getting a doctor to make up "bone spurs" in I-can't-remember-which-foot while waging his own "personal Vietnam" in New York sex clubs, bribing another doctor to sign off on a fake bill of health claiming "astonishingly excellent health", calling Tim Cook "Tim Apple" and Marilyn Hewson "Marilyn Lockheed" and then trying to deny he did so, trying to weasel out of the Access Hollywood tape by floating the suggestion it was not his voice even though he was on camera saying it, trying to claim getting more electoral votes than anybody since Reagan when his own VP got more than he did, hiding out in a hotel because it was raining while the rest of the European heads of state including the 92-year-old Queen of England went to honor WWI dead, declaring "England" and "the UK" are the same thing, walking in front of the Queen, calling Bhutan and Nepal "button and nipple", changing the course of a hurricane and sending it to Alabama with the power of a Sharpie, endorsing a child molester, lying about a news event he made up, then mocking the congenital disability of a reporter when that reporter wouldn't join him in that lie, contriving "three million illegals" because he didn't have the stones to deal with being on the short end of the popular vote, getting the name of his own trophy wife wrong, relentlessly coloring his own face a bizarre orange, dissing a debate moderator with a perverse menstruation hangup and then pouting at home because she'd be at the next one, dissing a TV commentator with the same menstruation hangup, splashing a full-page newspaper ad calling for the deaths of five innocent people who happened to be black or Hispanic, and then doubling down on stupid after they had been exonerated by DNA, being so arrogantly full of his own ass as to declare "I alone can fix it", "I know more than the generals", "I will be the greatest jobs president that god ever created" the supremely ironic "I'm very humble -- I'm humble in ways you wouldn't even understand", and citing himself as what he was thankful for on Thanksgiving; hiding at home sulking and twitting while the White House Correspondents Dinner(s) were going on because he's too much of a wimp to take the heat.

--- and as long as we've made it to the bottom... wait. make that "the end".... wait, no it was right the first time, now that we're at the bottom let's add having the Asshole Factor to ask for the most responsible job in the world after seven decades of never having held any kind of real job or position of responsibility at all in his life.
Of course this is an "including, but not limited to".
