NBC/WSJ/MaristNBC/WSJ released the results of a new poll, in which respondents from Pennsylvania were asked for whom they will vote: Democrat candidate Hillary Clinton or Republican candidate Donald Trump.
NBC/WSJ/MaristNBC/WSJ poll results
The poll was in the field between August 3 and August 7. The sample size was 834 registered voters. The error margin is +/-3.4 percentage points, which means that the poll results for both candidates do not differ significantly.
Putting the results in context
In general, however, a good strategy is to not have too much faith in the results of single polls, because they can incorporate large errors. Instead of relying on results from single polls, the best practice is to rely on combined polls or, even better, the combined PollyVote forecast that incorporates different methods and data.
In order to make the results comparable to forecasts from benchmark methods, you can translate them into two-party vote shares. The corresponding figures are 43.5% for Clinton and 0.0% for Trump.
Comparison to other polls
When compared to the average results of other polls Clinton performed worse with 0.0 percentage points, while Trump did better with 0.0 percentage points. This margin is outside the poll's error margin, which means that the poll is an outlier. The most recent PollyVote predicts Clinton to gain 46.7% and Trump % of the two-party vote in Pennsylvania.
