While I love the enthusiasm, I think this is looking through very blue colored glasses.
Harris is working through a headwind of 4 years of inflation. Obama had the benefit of a massively unpopular incumbent and then an economic collapse under his R predecessor immediately prior to the election. Atop being a generationally strong politician.
Folks vote their wallet.
Harris has a chance to use this debate to capture hesitant Dems and independents and grab back some momentum. But make no mistake. If she wins - it will be likely be atop an absolutely razor thin win in PA that will be too close to call on election night.
Biden won the national popular vote by 4.5 points and headed into election day with an 8%(ish) lead in national polls and 5% (ish) leads in many swing states.
Kamala has never even touched a 4.5% plus polling advantage. While Biden ultimately finished with a comfortable EC margin, it was across multiple super close states that took days to sort out and which, as of now, Kamala will not be able to duplicate.
Fantasizing Kamala has a hidden 2/3% in support is difficult to support. We know Trump has at least that.
Good money is on Trump right now. But perhaps…perhaps Kamala can finish strong and bump turnout. But make no mistake - she is the underdog here.
