Looks like we lost primarily due to low Democratic voter turnout

50. Lower turnout was absolutely the case

in Fairfax County, VA, which is a deep-blue stronghold.

In 2020, there were 605,023 votes cast for President in Fairfax County - 419,043 for Biden/Harris, 168,401 for Trump/Pence, 8,014 for Jorgensen/Cohen, and the remainder were either other candidates, write-ins, or over/undervotes (not delineated in the results). Turnout was 79.4%

In 2024, there were 561,368 voters (43,655 fewer than in 2020) - 365,654 for Harris/Walz, 173,320 for Trump/Vance, 14,884 for various third-party candidates, and 4,802 write-ins. This year, they also showed overvotes (569) and undervotes (2,149).
Turnout was 68.35%.

So, there was lower turnout, Harris/Walz received 53,389 fewer votes than Biden/Harris, Trump/Vance received 4,919 more votes than Trump/Pence, and 22,404 that voted either third-party, write-in, or over/undervote, an increase of 4,825 from 2020.

So we ended up, in a deep-blue bastion, with an 11 percentage point (or a nearly 14%) reduction in turnout, fewer votes for the Democratic candidate, more votes for the Republican candidate, close to or more third-party write-ins, and 2,149 people who didn't even bother to vote in the Presidential race.

I can't explain why the excitement wasn't there, but it appears that it wasn't.
