 A new poll from NPR, the PBS NewsHour, and Marist shows Biden and Trump remain statistically tied in a nationwide head-to-head matchup. Here's NPR's Domenico Montanaro. It found that Biden actually gained a point from last month's Marist survey when it was 49-49, dead heat between him and Trump. Now it's Biden ever so narrowly ahead, 50-48. Biden does slip a little when third parties are introduced, with Trump ahead by just one point.
