PPP (D) released the results of a new poll, in which respondents from West Virginia were asked for whom they will vote: Democrat Hillary Clinton or Republican Donald Trump.
PPP (D) poll results
The results show that 30.0% of interviewees would cast a ballot for former Secretary of State Hillary Clinton, whereas 57.0% would vote for real estate developer Donald Trump.
The poll was conducted from April 29 to May 1 with 1201 likely voters. Given the poll's error margin of +/-2.8 percentage points, the gap in voter support is statistically significant.
Putting the results in context
As any other method, polls are subject to bias. As a result, a good strategy is to not be too confident the results of an individual poll. Rather, one should check how a poll's results compare to benchmark forecasts.
To make the results comparable to forecasts from other methods, you can translate them into two-party vote shares. This procedure results in figures of 34.5% for Clinton and 65.5% for Trump.
Comparison to the combined PollyVote
The current PollyVote foresees Trump to gain 61.6% of the two-party vote in West Virginia. This means that Polly's combined forecast is 3.9 points below his polling numbers. Again, a look at the poll's margin of error shows that this difference is significant.
