I knew the story of Rachel Jackson (who died before Jackson was sworn in as our 7th President, so she was never technically a First Lady) before I was 12. But the main thing that bothers me is that Ann would have to ask. The savaging of Melania is just part of the vilification of Donald Trump (and the continuation of the 2016 Pots-Election Ethics Train Wreck) to sabotage his ability to govern and to discourage anyone from supporting him, working for him, working with him, or expressing praise or satisfaction regarding anything, literally anything, the President does, advocates or accomplishes.
Nah, there’s no mainstream media bias! Here’s how Melania is treated in Jack’s Facebook World, from a recent post by one of my Trump Deranged once-intelligent friends (in this case, from Harvard):
A recent hit piece in leftist mouthpiece Salon—which I no typically longer pay any attention to because its bias is so extreme and predictable—argues that General Dan ‘Razin’ Caine, chairman of the Joint Chiefs of Staff, is immoral and corrupt because he serves under the Commander in Chief and isn’t openly opposing him. Salon raves…
“But no president acts alone, not even Donald Trump. He needs military leaders, diplomats and senior officials to carry out his orders — orders that, in this case, were grossly immoral. Gen. Dan Caine, chairman of the Joint Chiefs of Staff, is one such man. Instead of opposing Trump’s threats to engage in potential crimes against humanity, Caine gave tacit consent for them, according to a report in the New York Times. It is an old story: Demagogues corrupt the people around them.”
It’s barely worth my time to rebut this garbage, except to say that it is the rationalization for the unethical conduct of the embedded progressive Deep State, and the “grossly immoral” orders Salon is whining about weren’t orders at all, but Trump’s deliberately harsh threats to wipe out Iran if it doesn’t capitulate soon. I only mention it because there are still many out there who are remarkably obtuse, including, I guess, Ann Althouse, and who refuse to acknowledge the corrosive affects of Trump Derangement, particularly as practiced by the Axis news media.
Ethics Alarms 
Althouse’s question seems to be particulary leading, anticipating that Melania should be the correct answer, but testing whether the A.I. could give this correct but politically incorrect answer.
Asking “which first lady’s” were accused of being “whores” does not not seem like the kind of question one can ask without being at least minimally informed about the accusations being heaved at the incumbent first lady. It seems much more likely a test of the AI than a genuine question.
I think I would sooner take the opinions of General Patton on fashion than the opinion of Salon on the Laws of Armed Conflict.
Thinking back through the First Ladies I can’t think of too many who came in for too much abuse, even though I can think of a few who theoretically could come in for legitimate criticism. Rachel Jackson may have broken the laws of marriage, but she had nothing to do with Andrew Jackson’s time in the White House. Dolly Madison isn’t really known for much other than helping save Washington’s picture when the British burned the White House. Zachary Taylor’s wife was something of a recluse. Mary Todd Lincoln had some mental health issues. The first First Lady I can think of really worthy of criticism was possibly Frances Folsom Cleveland, for marrying a 49-year-old president and obvious groomer when she was 21. However, that’s more personal failing than professional.
Edith Wilson, who Woodrow Wilson was smitten with to the point where he sang “Oh you great big beautiful doll” about her probably ruled the country illegally while he had suffered a disabling stroke and hid it from everyone who should have known. Eleanor Roosevelt was not exactly attractive and had a big mouth, but so what? Jackie Kennedy was annoyingly thought of as perfect, even though she wasn’t. Nancy Reagan came in for some attacks for her “just say no to drugs” campaign, which sounded good, but really wasn’t practical for some kids (witness the PSA where an African-American boy hides on his way home, and the voice of an African-American man says “to Kevin, and all the other kids who take the long way home, we hear you. Don’t give up”).
Barbara Bush didn’t come in for too many attacks until her husband was out of office. Even Laura Bush, who could have been targeted because she was responsible for the death of someone else while drunk, didn’t get that much abuse. Hilary is sui generis, but she put herself out there, and showed herself to be a cruel, selfish, lying tyrant who thought she was above the law and above everyone else. Michelle Obama came in for some abuse, but of course she was protected by the media. Jill Biden also got protection from the media she didn’t deserve, for basically being a gold-digger and elder abuser.
No one else was called a whore and worse. Melania is anything but an idiot, in fact she is fluent in no fewer than SIX languages. There is no credible evidence anywhere that she was ever a sex worker, although she did work as a model, which is nothing like that. Never mind though, the point is that the media and the left hate her, so they can throw whatever insults and hate at her that they want, and she just has to suck it up. I feel really sorry for the next GOP fit lady, who is going to come in for a huge amount of abuse, deserved or not.
Found what I want on my tombstone. (Sorry, I have nothing of substance to add to the conversation, but I appreciate you bringing this phrase to my attention.)
