PPP (D) published the results of a new poll. In this poll, participants from South Carolina were asked for whom they will vote: Democrat candidate Hillary Clinton or Republican candidate Donald Trump.
PPP (D) poll results
Of those who answered the question, 39.0% said that they will vote for former First Lady Hillary Clinton, whereas 41.0% indicated that they would give their vote to real estate developer Donald Trump.
The poll was conducted from August 9 to August 10 among 1290 registered voters. The sampling error is +/-2.7 points, which means that the poll results for the Republican and the Democratic candidate do not differ significantly.
Putting the results in context
Single polls may incorporate substantial biases, which is why they should be interpreted with caution. Rather than trusting the results from single polls, research in forecasting recommends to look at 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 other methods, you can translate them into two-party vote shares. The resulting figures are 48.8% for Clinton and 51.3% for Trump.
The poll in comparison with PollyVote's prediction
The current PollyVote forecasts Trump to gain 54.5% of the two-party vote in South Carolina. Hence, the PollyVote is 3.2 points above his polling numbers. Again, a look at the poll's margin of error indicates that this deviation is significant.
