And going back a few decades: Raymond Massey as Lincoln in Abe Lincoln in Illinois, Henry Ford as Young Mr. Lincoln and Walter Huston as Lincoln in Abraham Lincoln by D.W. Griffith. Plus Ralph Bellamy as FDR in Sunrise at Campobello and Nick Nolte as Jefferson in Jefferson in Paris. As for fictional Presidents, you could add Kevin Kline as Bill Mitchell in Dave.
there's also Jack Nicholson in Mars Attacks and Robin Wright in House of Cards (there was also Kevin Spacey in HoC, but sadly he's not advised to be mentionned nowadays)
President Mountain Dew Camacho was such a good character that it inspired a real President. Unfortunately that's not a joke.
Btw I wish Meryl Streep were here for her role in Don't Look Up too.
