It’s not unheard of, but in recent years it’s a rare occurrence when a president of the United States jettisons a vice president and runs with a new running mate while seeking re-election.

Newsweek magazine is reporting that Donald Trump’s key advisers are floating the notion of replacing Vice President Mike Pence with U.N. ambassador Nikki Haley.

Why? Because the vice president was highly critical of that hideous “Access Hollywood” tape in which the future president disclosed how he could grab women by their genitals. Pence, a devout Christian, reportedly was incensed over what he heard … and Trump hasn’t forgiven Pence for the apparent “disloyalty,” according to Newsweek.

I am not going to dictate what I think Trump should do. That’s his call. Frankly, the vice president’s future is of little interest to me, other than whether he would ascend to the presidency if — dare I suggest it — that Trump doesn’t finish his term.

The most recent president to switch VPs was Gerald R. Ford, who kicked Vice President Nelson Rockefeller — who was appointed to the office — to the curb. President Ford selected Sen. Bob Dole as his 1976 running mate. The president lost his bid for election to the office to which he was appointed to Jimmy Carter.

Newsweek reports: The president could be considering new strategies for his next campaign after Republicans were dealt major blows in last week’s midterm elections. Democrats picked up at least 36 seats to retake the House and prevented Republicans from further bolstering their lead in the Senate. This was an election Trump had turned into a referendum on his first two years in office.

Indeed, as I watched the returns roll in, it appears to many of us that Trump lost that “referendum” … bigly, if you know what I mean.

Does he toss the vice president overboard in some sort of hail-Mary effort to save his presidency? Not a damn thing would surprise me.
