Hillary sharpens, Trump softens

WASHINGTON — If you are the status quo candidate in a change election in which the national mood is sour and two-thirds of the electorate think the country is on the wrong track, what do you do? Attack. Relentlessly. Paint your opponent as extremist, volatile, clueless, unfit, dangerous. Indeed, Hillary Clinton’s latest national ad, featuring major Republican politicians echoing that indictment of Donald Trump, ends thus: “Unfit. Dangerous. Even for Republicans.”
