Carter is the only one I can think of.
Kennedy and Carter where the last two presidents that have served in the Military and some of the moonbats don;t like John Kennedy all tha tmuch since the right keeps reminding them of the fact that Kennedys economic policies are just like most Cconservatives.
These are Since WWIIRepublican Presidents:George Bush - Air National Guard
George H.W Bush - Nay, WWII
Ronald Reagan - Army, WWII
Gerald Ford - Navy, WWII
Richard Nixon - Navy, WWII
Dwight D. Eisenhower - WWII
Democrats Presidents:obama - None
Clinton - None
Jimmy Carter - Navy, Served during Korea, but didn't go to Korea.
Lyndon Johnson - Navy, WWII
John F. Kennedy - Navy, WWII
Harry S. Truman - Army, WWI
So, looking at that, every Republican President Since WWII has served in the military. Not so much for the Dems....Captain Zero has no room to talk.
