I agree that the rational and correct choice was still Harris. I voted for Harris and told others to vote too.

If you're talking about the turnout of the general public, my point is that running on being the 'lesser evil' and moving to the right in an attempt to get republican votes is not a successful method to motivate tens of millions of Americans to get out and vote, even if the greater evil is Fascism. Americans are overworked and uneducated. It's the campaigns responsibility to motivate them to vote by offering them policies that will improve their daily livelihood. It's ultimately on the campaign to earn those votes. The data is clear that progressive policies are popular with everyone, that includes Republicans and independents on top of Democrats. The decision to take those voters for Granted without offering them enough on the policy front, and instead move to the right, was a calculated decision by the campaign that failed.

If you're talking specifically about the turnout of Arab/Muslim voters in swing states, I discussed that here. Harris' decision to take those votes for granted by refusing to break from Biden was again a calculated decision that did not pay off. All the data showed that if she did break from Biden and call for an Arms Embargo, which is very popular, she would have gotten significant gains.
