Precincts where GOP House candidates got <1% of the vote in 2018?

Question

I was thinking about this question about the 2016 presidential election. I was thinking about the results of the 2018 midterms. I was thinking about that question, but a little bit differently as like this:

1. The district is contested and there is a Republican running. We don't want any precincts where the Dem gets 100% of the vote except for write-ins because there isn't a Republican running.
2. There were >= 250 votes cast. This is done to make sure that there is less volatility in the result.

I want to see the results for this. I want to know if there were more such precincts in 2018 than in 2016.

Answer 1

Using the MIT 2018 precinct dataset in its current state at time of writing, I found sixty precincts which match your criteria. Thirty-nine were in New Jersey, mostly in Essex County - ten were in Missouri, seven in Alabama, two in South Carolina, and one each in Virginia and North Carolina.

Note that precinct data is extremely hard to analyse due to different reporting standards between local authorities - some record write-ins as separate precincts, some record votes which came from voting machines separately, and so on.

While interpreting the data below you should bear in mind the caveats attached to the MIT dataset - for example, it only contains data from 44 states. In particular, no data from New York is included, which helps explain why the number of precincts is significantly fewer than in the answer to the 2016 question.

However, the MIT data appears to be the most complete publically available precinct-level dataset, so that is what I've made do with.

The results from these sixty precincts are below, sorted by State, County, and then Republican %:
