On foreign policy, there is some coming together between Clinton and her Republican allies. Dovish liberals worry about this aspect of the anti-Trump right. They suspect — partly on the basis of her history — that Clinton’s instincts are more hawkish than President Obama’s.

Her allies on international issues cast the issue somewhat differently — and more positively: that Clinton’s election could restore something close to an older consensus on foreign policy that was blown apart by the Iraq War. They argue that she occupies a middle ground between Obama and his hawkish critics. She is less interventionist than the neoconservatives but would, on some issues, be tougher in her approach to diplomacy than Obama has been.

Any long-term electoral effect of the rise of Clinton Republicans is likely to be felt among the white college-educated voters whom Trump has so alienated. Trump’s turn to the hard right, reinforced by his hiring of Breitbart’s Stephen Bannon as his campaign chief executive, could further aggravate the GOP’s problem with such voters. Trump muddled his position on immigration to try to win some of them back.
