Monday night's presidential debate changed nothing fundamental about the race for the White House. Hillary Clinton was confident, cool, unflappable, possessing an easy mastery of policy detail across a range of subjects, as well as of her opponent's multitude of vulnerabilities. Donald Trump, meanwhile, was very much himself: hostile, erratic, easily baited by Clinton's provocations, prone to hyperbole and exaggeration, and amazingly adept at lying shamelessly. That sounds like a Clinton wipeout.
