I don't think that's a good measure, to be honest. If Biden won every single county by 51%, by this metric you could argue 100% of the economy voted for Biden.

I don't think that's a good measure, to be honest. If Biden won every single county by 51%, by this metric you could argue 100% of the economy voted for Biden. In reality, 51% voted for Biden. Also, I'm sure tech companies have an out-sized "GDP" metric. That being said, I believe 70% is probably fair, because most of the high earners support democrats. Just pointing out an issue in the counting.
