Bill Clinton (Hillary Clinton)

George Bush Sr (Barbara Bush)

Gerald Ford (Betty Ford)

Richard Nixon (Pat Nixon)

Lyndon B Johnson (Lady Bird Johnson)

Is it rare for a President to be married more than once?

Added (1). I have no knowledge of the current President but I was referring to Reagan as he was married to both Nancy Reagan and an actress before her

Yes

It used to be rare all across society.

Republican poster-boy Reagan was.

Yes

Reagan was the first one who was divorced and remarried. We've had a few unmarried.

Some widowed Presidents (Tyler, Wilson) remarried and two divorced (Reagan, Trump).

There were some who married twice. I think including John Tyler (as I've heard on a video).

And, James Buchanan ended up never marrying once.

Best to just have affairs like JFK and Clinton
Really what the heck does this have to do with anything

Yeah.

Because a president is as human as the rest of us, why do you think he is perfect and be above all that?
