Results of a new poll carried out by PPP (D)PPP (D) were announced. The poll asked interviewees from South Carolina for whom they will vote: Democrat candidate Hillary Clinton or Republican candidate Donald Trump.
PPP (D)PPP (D) poll results
Of those who responded, 39.0% said that they are going to vote for former First Lady Hillary Clinton, while 41.0% revealed that they would give their vote to billionaire Donald Trump.
This poll was conducted from August 9 to August 10, among a random sample of 1290 registered voters. The sampling error is +/-2.7 percentage points, which means that the levels of voter support for Clinton and Trump do not differ significantly.
Putting the results in context
Single polls should be interpreted with caution, because they can contain large errors. At least, one should check how a poll's results compare to benchmark forecasts.
In order to make the results comparable to benchmark forecasts, we translate them into two-party vote shares. This yields figures of 48.8% for Clinton and 51.3% for Trump.
Results in comparison to other polls
Trump is currently at 51.1% of the major two-party vote according to an average of recent polls in South Carolina. Relative to his numbers in the PPP (D)PPP (D) poll Trump's poll average is 0.3 percentage points worse. This difference is within the poll's margin of error, which means that the poll is not an outlier.
The poll in comparison with PollyVote's forecast
The most recent PollyVote predicts Trump to gain 53.8% of the two-party vote in South Carolina. This means that Polly's forecast is 2.5 points above his polling numbers. Again, a look at the poll's sampling error shows that this deviation is negligible.
