With the current info on Undecideds, it's lining up mostly with what I guessed based on what we knew about the locked in voters barring another polling disaster rendering all the data moot. Around 60% of the recent undecideds have broke for Harris, but the bulk of Undecideds who committed earlier broke for Trump (52-48) which is a larger number. These two average out to basically 50-50 on the whole. Undecideds went massively for Trump both previous elections so I don't foresee Harris breaking 50%ish, that's already a big gain.
This is relevant because the final locked in scores at the rate things are trending are going to be something like 47.5 - 49 give or take a half a point by election day. Not all of the 3-4 points left are going to either them, at least one, maybe 2 are going for Third Parties, which unlike in past years are way more left leaning than normal thanks mostly to RFK Jr and Libertarian infighting. Harris is trending in the right direction, but that 3rd party shift absorbs some of that. A final 50/50 call between what's left leaves maybe a 2 point difference final result depending on exactly how well third parties do. 48-50 or so. That's a Hilary Clinton sized margin between Popular Vote and EC. Not a death sentence, this thing is cyclical, sometimes it favors one party or another (Democrats had a EC advantage in 2004 and 2008 and probably 2012) and sometimes it's stronger. The effect is supposed to be much less this year, a Biden level margin of 4 points or even a 3 point lead is a safe Kamala win. Not so much 2 points, that's up in the margins.
If the polling is right, this is a dead heat election where Wisconsin and Michigan are going blue, Arizona Georgia and North Carolina going red, and Nevada and Pennsylvania are too close to call.
