CBS News reports:
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.
In Iowa, the two are even, each with 40 percent support. This is the only state in recent polling that doesn’t show Clinton with an outright lead. In some ways, the tie there just spotlights Trump’s difficulty breaking out beyond his base, more generally. Iowa has many older voters and Trump does well with them. In Iowa, as in Ohio, older voters say that American life is changing for the worse. However Trump is struggling with younger voters, the youngest of whom are the most likely to disagree with that assessment.
