PPP (D) released the results of a new poll, in which respondents from Washington were asked for whom they will vote: Republican Donald Trump or Democrat Hillary Clinton.
PPP (D) poll results
Of those who responded, 49.0% said that they are going to vote for former Secretary of State Hillary Clinton, while 37.0% revealed that they would give their vote to real estate developer Donald Trump.
The poll was carried out between June 14 and June 15. The sample size was 679 likely voters. The margin of error is +/-3.8 points. This means that the poll results for the two candidates differ significantly.
Putting the results in context
As any other method, polls are subject to bias. Therefore, as a general rule, a good strategy is to not have too much confidence in the results of a single poll. At the very least, one should check how a poll's results compare to benchmark forecasts.
For the following comparison, we convert Clinton's and Trump's raw poll numbers into shares of the two-party vote. This procedure results in values of 57.0% for Clinton and 43.0% for Trump.
Comparison to the combined PollyVote
The current PollyVote expects Clinton to gain 57.5% of the two-party vote in Washington. That is, Polly's forecast is 0.5 points above her polling numbers. Again, a look at the poll's sampling error shows that this deviation is negligible.
