PPP (D) published the results of a new poll. In this poll, participants from West Virginia were asked for whom they will vote: Hillary Clinton or Donald Trump.
PPP (D) poll results
Of those who answered the question, 30.0% said that they would vote for former First Lady Hillary Clinton, whereas 57.0% declared that they would give their vote to real estate developer Donald Trump.
The poll was in the field between April 29 and May 1. The sample size was 1201 likely voters. Considering the poll's margin of error of +/-2.8 percentage points, the spread in voter support is statistically significant.
Putting the results in context
As any other method, polls are subject to bias. In general, you should not focus too much on the results of an individual poll. Instead of trusting the results from single polls, you should rely on combined polls or, even better, the combined PollyVote forecast that incorporates different methods and data.
For the following comparison, we translate Trump's and Clinton's raw poll numbers into shares of the two-party vote. This yields figures of 34.5% for Clinton and 65.5% for Trump. On September 8 Clinton received 65.5% in the PPP (D) poll and Trump received only 0.0%.
The poll in comparison with PollyVote's forecast
The most recent PollyVote forecasts Trump to gain 62.1% of the two-party vote in West Virginia. This means that Polly's forecast is 3.4 points below his polling numbers. The PollyVote forecast is therefore outside the poll's error margin.
