Right about now I’m thinking: Laura Bush, with Jacqueline Kennedy Onassis in 2nd.
I can’t remember ever seeing any of the pre-1900 first ladies, but man it’s no contest. Jackie Kennedy all the way. Man I thought she was hot.
And if we’re going to go for “hottest President’s mistresses” hands down it goes to Marilyn Monroe. Hoooooooooo Boy!
Eleanor Roosevelt? 
Angelica Singleton Van Buren, daughter in law of Martin Van Buren, was a beautiful woman. Van Buren was a widower so she was not technically First Lady, but I’ve seen pictures of her and she is striking. She was also Dolley Madison’s niece, so she was also probably a lot of fun as well.
Put me down for Hillary.
You know, I always dug Hillary Clinton, especially the last few years with that shorter haircut of hers (though she hasn’t looked good lately). When you look at pictures of her from 20 years ago, and then from the last year or so, wow, she’s gotten better with age!
Laura Bush looks good in those short skirts, but she’s kind of a butterface.
Jackie O was definitely a babe, I’ll agree with that.
There’s some First Ladies who never were too that I’ve checked out: Liddy Dole for some reason I thought was pretty attractive for an older woman, and I’m trying to remember if Kitty Dukkakis was hot or not.
John McCain’s wife is smoking.
Does anyone remember what Mrs. Mondale looked like? I know Eleanor Mondale is supposed to be very pretty.
Of course none of them hold a candle the True First Lady . . my wife!!!
That’s easy.
Grover Cleveland’s wife, I think her name was Francis. She was only 21 or so when she got married to Cleveland.
The sick thing was that he more or less raised the girl, she was a bit like a niece to him.
She was a real cutie, though.
Ok, I looked it up and Cleveland’s wife was named Frances, the only First Lady to have given birth while living in the white house.
There’s a picture of her on this site:

I dig that dress!
