PPP (D) published the results of a new poll on October 24. In this poll, interviewees from West Virginia were asked for whom they will vote: Republican Donald Trump or Democrat Hillary Clinton.
PPP (D) poll results
Of those who answered the question, 30.0% said that they plan to vote for former Secretary of State Hillary Clinton, whereas 57.0% said that they would give their vote to real estate developer Donald Trump.
The poll was conducted from April 29 to May 1. A total of 1201 likely voters responded. There is a sampling error of +/-2.8 percentage points. Considering this error margin, the gap between both candidates is statistically significant.
Putting the results in context
Single polls should be interpreted with caution, as they may incorporate large biases. Instead of relying on results from single polls, one should rely on combined polls or, even better, the combined PollyVote forecast that relies on different methods and data.
In order to make the results comparable to benchmark forecasts, you can convert them into two-party vote shares. The respective figures are 34.5% for Clinton and 65.5% for Trump.
Comparison to the combined PollyVote
The current PollyVote predicts Trump to gain 61.7% of the two-party vote in West Virginia. This means that Polly's combined forecast is 3.8 points below his polling numbers. Again, a look at the poll's sampling error indicates that this difference is significant.
