The last 48 hours have no precedent in US politics. People have only just started to absorb what it means for President Biden to drop out of the election and Vice President Harris to take his place (which she has almost certainly done, based on delegate counts--and the endorsements of both the House Minority Leader and Senate Majority Leader). No polling data released before Thursday will have captured any of that.
I will say, however, that I feel so much better about the election than I did Sunday morning, I believe we will win it. Clearly, I'm not alone.
The election is 15 weeks from today. That's 13 weeks longer than most people pay attention. And given how much has happened in just the last 4 weeks, a lot more can happen before November.
But for the first time in a while, I feel great about our chances.
