WBUR/MassINC published the results of a new poll. In this poll, participants from Massachusetts were asked for whom they will vote: Hillary Clinton or Donald Trump.
WBUR/MassINC poll results
According to the results, 60.0% of interviewees will cast a ballot for former Secretary of State Hillary Clinton, whereas 31.0% would vote for businessman Donald Trump.
The poll was conducted from September 7 to September 10. A total of 506 likely voters responded. Considering the poll's margin of error of +/-4.4 percentage points, the difference between both candidates is statistically significant.
Putting the results in context
Individual polls often incorporate substantial biases, which is why they should be interpreted with caution. At least, one should check how a poll's results compare to benchmark forecasts.
To make the results comparable to benchmark forecasts, we convert them into shares of the two-party vote. The resulting figures are 65.9% for Clinton and 34.1% for Trump.
Comparison to other polls
Looking at an average of Massachusetts polls, Clinton's two-party vote share is currently at 63.2%. This value is 2.7 percentage points lower than her respective numbers in the WBUR/MassINC poll. This difference is within the poll's error margin, which means that the poll is not an outlier.
The poll in comparison with PollyVote's prediction
The most recent PollyVote forecasts Clinton to gain 63.9% of the two-party vote in Massachusetts. This means that Polly's prediction is 2.0 points below her polling numbers. Again, a look at the poll's margin of error reveals that this deviation is negligible.
