PPP (D) published the results of a new poll. In this poll, respondents from West Virginia were asked for whom they will vote: Democrat Hillary Clinton or Republican Donald Trump.
PPP (D) poll results
Of those who answered the question, 30.0% said that they intend to vote for former New York Senator Hillary Clinton, while 57.0% indicated that they would give their vote to billionaire Donald Trump.
The poll was in the field between April 29 and May 1. The sample size was 1201 likely voters. Taking into account the poll's margin of error of +/-2.8 percentage points, the spread in voter support is statistically significant.
Putting the results in context
Single polls often include substantial errors, which is why they should be interpreted with caution. At least, one should check how a poll's results compare to benchmark forecasts.
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.
Results compared to the combined PollyVote prediction
The most recent PollyVote predicts Trump to gain 62.0% of the two-party vote in West Virginia. This means that Polly's combined forecast is 3.5 points below his polling numbers. Again, a look at the poll's error margin suggests that this deviation is significant.
