I’ve tried using LLM’s to do the same exact thing (turning precinct-level election results into a spreadsheet) and in my experience they worked rather poorly. Less accurate than traditional OCR, and considering how many fixes I had to make, altogether slower than manual entry. The resolution of the page made an outsized difference. It’s nice that you got it to work, but I am skeptical of it as a permanent solution.

Tangentially- I appreciate what OpenElections does- however, I wish there was a similar organization that did not limit themselves to officially certified results. There are already other organizations who collect precinct results post-2016, and using only official results basically limits you to 2008 and afterwards, but historical election results are the real intrigue. Not to mention that I have noticed many blatant errors in election results that have supposedly been “certified” by a state/county government. The precinct results Pennsylvania publishes, for example, are riddled with issues.
