Results of a new poll carried out by PPP (D) were spread. The poll asked respondents from West Virginia for whom they will vote: Hillary Clinton or Donald Trump.
PPP (D) poll results
According to the results, 30.0% of interviewees plan to give their vote to former Secretary of State Hillary Clinton, while 57.0% intend to 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. 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
Single polls can contain substantial biases, and should be interpreted with caution. At the very least, one should examine how a poll's results compare to benchmark forecasts.
To make the results comparable to benchmark forecasts, you can translate them into two-party vote shares. This procedure results in figures of 34.5% for Clinton and 65.5% for Trump.
The poll in comparison with PollyVote's prediction
The current PollyVote predicts Trump to gain 62.1% of the two-party vote in West Virginia. That is, the PollyVote forecast is 3.4 points below his polling numbers. Again, a look at the poll's error margin suggests that this difference is significant.
