Americans disapprove of the way Donald Trump handled his run-in with Khizr Khan, the Gold Star father whose son was killed in Iraq in 2004, by a ratio of 74-13. Republicans disapprove by a 61-22 margin, Independents by a 68-16 margin and Democrats by a margin of 90-3.

These numbers ought to scare the hell out of the go-along wing of the Republican Party, as this incident will most likely define the campaign from here on.
