WBUR/MassINC released the results of a new poll, in which respondents from Massachusetts were asked for whom they will vote: Republican nominee Donald Trump or Democrat nominee Hillary Clinton.
WBUR/MassINC poll results
According to the results, 60.0% of participants intend to give their vote to former New York Senator Hillary Clinton, whereas 31.0% are going to vote for real estate developer Donald Trump.
The poll was conducted from September 7 to September 10. A total of 506 likely voters responded. There is a sampling error of +/-4.4 percentage points. Considering this error margin, the gap between both candidates is statistically significant.
Putting the results in context
Single polls should be interpreted with caution, as they often include substantial biases. Rather, one should examine how a poll's results compare to benchmark forecasts.
In order to make the results comparable to benchmark forecasts, you can convert them into shares of the two-party vote. This procedure results in figures of 65.9% for Clinton and 34.1% for Trump.
Results in comparison to other polls
If we look at an average of Massachusetts polls, Clinton's two-party vote share is currently at 61.7%. This value is 4.3 percentage points lower than her respective numbers in the WBUR/MassINC poll. This deviation is within the poll's margin of error, which means that the poll is not an outlier.
The poll in comparison with PollyVote's prediction
The latest PollyVote foresees Clinton to gain 63.6% of the two-party vote in Massachusetts. This means that Polly's forecast is 2.3 points below her polling numbers. The PollyVote forecast is therefore within the poll's sampling error.
