If you've been following our precinct-level data closely, you might have noticed some updates last week! We've now added Hawaii, New Mexico, and Kansas to the 2024 dataset. Check out all of our available states on our GitHub: buff.ly/2hC9xOv

Most states are still colored grey, indicating that our team hasn't yet cleaned and posted their precinct-level election results. 17 states are now bright pink, indicating that we HAVE collected, cleaned, and posted their data! Pink states are: MT, MN, SD, NH, IL, KY, TN, VA, DE, NC, SC, DC, FL, NM, OK, KS, and HI.
