It was Harrison Ford, obviously.

Here I was thinking Dwight Garfield.

Maybe Andrew Garfield?

Both names are last names. That’s a big clue.

First name has to be Grant or Jackson right? Maybe Wilson, potentially Adam if you stretch it.

Last name could be anything. I’m going with Jackson Adams - seems like a regular name, common last name, just hoity toity enough for a nickname like prez to stick.

I made some comments here https://news.ycombinator.com/item?id=33463317 when someone else mentioned the two last names thing

didn't think of Adams, the thing is do people think of Adams the president when hearing Adams the last name. I think the first thing to spring to mind would be The Addams family. I think both names should be so obviously associated with President's in the mind that it just be like - Heyyy, it's Prez -

Washington Jefferson for example.

on edit: although I think some names like Washington would be sort of messed up to give your kid, but hey who am I to throw stones - I named my daughter Coraline.

If we're going to guess, I'm going with Roosevelt van Buren.

Nixon Cleveland?

Randolph Davis??

both his First and Last names were last names of two presidents

hmm, what Presidential last names work best as first names, not McKinley or Hoover...

Kennedy Grant Garfield (although hard to imagine a guy named Garfield getting the Prez nickname) Fillmore? Jefferson Washington Wilson Jackson

also what ones would be commonly known presidential names and maybe the first thing one thinks of when hearing the name is the President - Kennedy for sure, but Grant is a common enough name that I don't think of Ulysses when I hear it.

My impression was that in the US, any surname can be used as a first name. Wasn't there even someone with Mackenzie as first name? Plenty of Harrisons, Taylors and other names that really don't sound like a first name.

Truman isn't too uncommon as a first name. Harry S. Truman was a president.

Wow this blew up. How about a hint - both presidents had trouble with impeachments. But NOT trump (again, think 2001) I looked him up on LinkedIn, and he's not there. Speak up Prez if you're here!

Clinton "Clint" Johnson.
