Polls suggest Donald Trump's economic policies have hit voters hard, and Democrats are eyeing seats across the country, including in states they haven't won in decades. With redrawn voting maps, a fresh wave of progressive candidates, and Donald Trump making some eyebrow-raising promises, there's a lot at stake before polling day on November 3.
