In Ohio, which is so critical to Donald Trump’s electoral fortunes, it is Hillary Clinton who has extended her lead and is now up six points, 46 percent to 40 percent; she was up four points in July. Clinton has made gains among women, and remains bolstered by a nearly-unified Democratic base. She wins 90 percent of Democrats, while Trump remains hampered by just enough reluctant Republicans: He’s at 79 percent of GOPers.
