According to MIT Election Data and Science Lab's U.S. President Precinct-Level Returns 2016 dataset, there were around 580 such precincts (the precise number is difficult to count as some counties seem to report write-ins, etc as separate precincts). For example:
- Davidson County's 601 precinct in Tennessee gave 1207 votes out of 1277 to Evan McMullin, and none to either Trump or Clinton.
- Larimer County's 2145235206 precinct in Colorado gave 965 votes out of 1111 to Clinton, and most of the rest to Gary Johnson or Jill Stein.
Here is a summary of the precincts where Trump's vote share was less than 1%, though as I said there may be some mistakes due to how certain types of votes are counted.
