Now that Donald Trump has the Republican presidential nomination in hand, he is weighing his choice for a running mate, considering some of his defeated 2016 rivals as well as someone with governing experience with whom he would be personally compatible.
He has put one of those rivals, retired neurosurgeon Ben Carson, on his team to help him decide, and Carson himself has said he'd be willing to consider taking the job. If he were to get it, it would be a rerun of the 2000 phenomenon, when GOP nominee George W. Bush tapped his father's secretary of defense, Dick Cheney, to vet the prospects, and Cheney chose himself.
Trump in an interview with the New York Times said he likes another former rival who was the last to drop out of the 2016 race, Ohio Gov. John Kasich, but "I'm not sure John even wants it."
Still another recent rival, New Jersey Gov. Chris Christie, helped cut down Florida Sen. Marco Rubio in a debate by exposing him as a robotic candidate and then endorsed Trump. Christie's fiery temper would seem to fill nicely the compatibility factor.
