- No way of getting around this: What we’re now seeing in the campaign is at the very outer bounds of what I thought was possible with a Biden-to-Harris switch. We’re now looking at a four-to-five point move in Harris’ direction over just two weeks. My bullish scenario was Harris resetting the campaign to the status quo ante before the big debate — at which point Biden was not in a bad position but was clearly if slightly behind. From there, a more dynamic Harris campaign uses the remaining three months of the campaign to battle its way into a lead. That’s not what we’re seeing. Harris is holding all of Biden’s strength in the Blue Wall states, adding to it and then also moving the southern tier states into contention. Her current popular vote margin is moving into the range a Democrat needs to win the election.
