"... But until the actual convention, it’s just talk. For all the attention being paid them, polls purporting to show how Hillary Clinton (or even Sanders) would do against various possible Republican nominees are meaningless at this point in the campaign. (After the two parties’ conventions in 1988 Michael Dukakis was running eighteen points ahead of George H. W. Bush.) And no one should be under the illusion that the nomination could be denied Trump without causing a civil war within the Republican party. Trump commented on Wednesday of this week that if the nomination is taken from him, “You’d have riots.” If he’s the nominee there remains that possibility of a third party formed, among other things to give Republican politicians a place to go until the storm blows over. But whatever ultimately becomes of their candidacies, Donald Trump and Bernie Sanders are atop movements that won’t go away. And whoever ends up in the Oval Office will have a devil of a time trying to govern."
