Until these Republicans like Pence, Christie, Sununu, who are now getting credit for criticizing Trump, can say they will not support a nominated Trump for election instead of hedging and saying that Trump won’t get the nomination, you can ignore their statements as worthless. All candidates who make it to the debate stage will be asked if they will support whoever is nominated, and they will all check that box - except, of course, Trump!
@johnldeboer Excellent point.
