PPP (D) released the results of a new poll, in which respondents from West Virginia were asked for whom they will vote: Donald Trump or Hillary Clinton.
PPP (D) poll results
According to the results, 30.0% of participants intend to vote for former First Lady Hillary Clinton, whereas 57.0% would vote for real estate developer Donald Trump.
This poll was conducted from April 29 to May 1, among a random sample of 1201 likely voters. The error margin is +/-2.8 points. This means that the poll results for both parties' candidates differ significantly.
Putting the results in context
Individual polls can incorporate substantial biases, which is why they should be treated with caution. Rather than trusting the results from single polls, the evidence-based approach is to look at combined polls or, even better, the combined PollyVote forecast that relies on different methods and data.
In order to make the results comparable to forecasts from benchmark methods, one can translate them into two-party vote shares. This procedure results in values of 34.5% for Clinton and 65.5% for Trump.
The poll in comparison with PollyVote's prediction
The most recent PollyVote foresees Trump to gain 62.4% of the two-party vote in West Virginia. This means that the PollyVote forecast is 3.1 points below his polling numbers. Again, a look at the poll's margin of error shows that this difference is significant.
