Our forecasts don’t produce a single expected vote share for each candidate, but rather generate a range of possible outcomes, shown below. The range will be wider or narrower under certain circumstances: For instance, it narrows as the election gets closer. Our estimate of each candidate’s chance of winning the state is based on these ranges.

There’s no forecast for West Virginia yet because there isn’t enough recent polling.


Nonetheless, we’re tracking polling results as they come in, calculating a weighted polling average for each candidate.

The weights account for the quality of each poll based on its track record and its methodological standards. They also account for sample size and how recently it was conducted; recent polls are weighted much more heavily than older ones. Polls are also adjusted for house effects, which is a tendency to consistently show different results for a candidate than the average of other polls.

For the West Virginia Republican primary, we’ve collected three polls. Here they are, ranked by how heavily they factor in to our latest polling averages.
