https://www.nytimes.com/interactive/2024/05/16/us/elections/biden-trump-donors.htmlThese 2 maps show the net change in donors by county from the 2020 cycle. In general, the number of Trump donors hasn't changed much from 2020 whereas Biden has seen an increased number of donors since 2020. However, one confounding variable that in 2020 Dem donors were split between multiple candidates as the primary played out.
Another thing to consider is that it's hard to extrapolate how meaningful these giant spikes are. LA County has a giant spike as Biden has gained nearly 5000 more voters since 2020, however, in the context of a County of 10 million people, that might not be very meaningful.
With that being said, there are many aspects of this graph which align with conventional wisdom. For instance, the biggest positive Trump spikes are in places where the GOP has gained in recent cycles (Miami-Dade, Long Island) or fast growing GOP strongholds (Mohave County AZ, Horry County SC, parts of Utah and Idaho, ect).
Trump has seen declines in most of the metros that shifted hard against him in 2020 (Denver, Atlanta, Dallas, ect). I wonder if some of this is some Rs unhappy with Trump in these areas donating to Haley instead.
For Biden, the biggest spikes almost universally come from urban areas and honestly where the green spikes are seem to correlate with the 2016-->2020 swing map quite a bit. Many of the biggest spikes seem to be in white-liberal bastions like Seattle, Austin, Denver, Twin Cities, Boston, ect. whereas Dem cities with larger non-white populations haven't held up quite as well like Dallas, Atlanta, Las Vegas, NYC, ect. Also seems like there's pretty big dropoffs in the Philly and DC areas which is interesting considering both have a lot of white liberals.
Again, because the number of donors relative to the overall population is small and likely unrepresentative, I wouldn't read into this too much but still interestingly. Also another one of those smaller metrics that at least topline suggests Biden should be fine in re-election despite polls.
Thoughts?
