PPP (D) released the results of a new poll, in which respondents from West Virginia were asked for whom they will vote: Republican nominee Donald Trump or Democrat nominee Hillary Clinton.
PPP (D) poll results
The results show that 30.0% of interviewees will cast a ballot for former First Lady Hillary Clinton, whereas 57.0% would vote for businessman Donald Trump.
The poll was carried out between April 29 and May 1. The sample size was 1201 likely voters. 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
Individual polls may include large biases, and should be treated with caution. At the very least, one should check how a poll's results compare to benchmark forecasts.
In order to make the results comparable to forecasts from benchmark methods, you can translate them into two-party vote shares. This yields figures of 34.5% for Clinton and 65.5% for Trump.
Comparison to the combined PollyVote
The current PollyVote foresees Trump to gain 62.3% of the two-party vote in West Virginia. That is, the PollyVote is 3.2 points below his polling numbers. Again, a look at the poll's margin of error shows that this difference is significant.
