Do you remember the last time a congressman was elected president? Hint: He wore a stovepipe hat, grew a beard just before swearing-in and oversaw the civil war...
Under that criteria, JFK was the last before bammie.
Not trying to get into an argument but now you're changing things up, I was responding to your original statement....taint no thang :)
President Kennedy was later a senator, Presidents Nixon and Lyndon Johnson were later senators and vice-presidents, but President Lincoln was only a congressman. Sorry if I wasn’t chrystal clear.
