As of yesterday, a little over 7.5 million Texans had voted.
If we assume each county has the same partisan tilt today as it did in 2020, Kamala has 45.6% of the vote so far (3,425,767).
If we go by my calculated guestimate for each county's evolving partisan shift since 2012, Kamala has 47.8% of the vote (3,591,567).
If we go by Huckleberry's alteration that "dampens" the partisan shift, Kamala has 46.6% of the vote (3,501,382).
Right now, based on the partisan swing in each county and according to their turnout, Harris likely won't win Texas ranging from 45.6% to 47.8% of the vote. In 2020, Biden won 46.5%.
However, her odds are improving as more EV data come in. For example, Huckleberry's formula had Kamala winning 46.3%, while my formula had her with a 47.5% chance yesterday.
Below is the revised map of EV turnout. As of yesterday, 40.35% of registered Texans had voted. The overall pattern hasn't changed, but when I looked at the updated figures, it appears like some counties are plateauing and others are catching up. That applies to almost everywhere except amongst the worst laggards, who are falling further behind.
