U.S. Sen. Marco Rubio finds himself defending an unusual political position.

The Florida Republican stands by his comment that GOP presidential nominee Donald J. Trump is a “con man” who shouldn’t be president of the United States.

But he’s going to vote for him anyway.

Some observers in Florida and elsewhere are quizzing the one-time GOP presidential primary candidate who, during the campaign, said some amazingly harsh things about the man who defeated him — and 15 other contenders — for the party nomination.

Rubio isn’t back away from any of them.

But he’s voting for Trump … he says.

This well might summarize the state of the 2016 presidential campaign.

Many rank-and-file “establishment” Republicans can’t stomach the candidacy of Trump, but they truly detest — even hate — the Democratic nominee, Hillary Rodham Clinton.

Lesser of two evils? This is it, according to Sen. Rubio.
