Wow. Looks like Biden is capturing the undecided vote. I'd say the poll was unreliable if Trump was at like 35 to get a Biden+16 result, but Biden getting this high of the vote share is extremely, awful, no-good, horrible news for Trump. Biden is still a heavy favorite to win this election. If we continue to see double-digit polls for Biden in a couple weeks, we're going to be talking about a whole new round of "swing states" come election day.
That's exactly why this isn't 2016. 4 years ago, undecideds, who disliked both candidates, heavily broke for Trump. That's why HRC leading a poll 45-40% was worth much less than Biden being close or above in state polls. We already had indications months ago that voters disliking both candidates go for Biden. I could imagine a lot of them being exhausted and are tired of Trump's ongoing reality show. They don't want to hear from the prez and his scandals every day.
