WBUR/MassINC released the results of a new poll, in which respondents from Massachusetts were asked for whom they will vote: Donald Trump or Hillary Clinton.
WBUR/MassINC poll results
Of those who replied, 60.0% said that they are going to vote for former New York Senator Hillary Clinton, while 31.0% revealed that they would give their vote to businessman Donald Trump.
This poll was conducted from September 7 to September 10, among a random sample of 506 likely voters. If one accounts for the poll's sampling error of +/-4.4 percentage points, the spread between both candidates is statistically significant.
Putting the results in context
In general, however, don't have too much faith in the results of single polls, as they may incorporate large errors. Rather than trusting the results from single polls, the evidence-based approach is to use combined polls or, even better, a combined forecast that uses different methods and data.
In order to make the results comparable to forecasts from other methods, one can convert them into two-party vote shares. The respective figures are 65.9% for Clinton and 34.1% for Trump.
Comparison to other polls
Clinton is currently at 63.5% of the major two-party vote in an average of recent polls in Massachusetts. This value is 2.4 percentage points lower than her corresponding numbers in the WBUR/MassINC poll. This margin is within the poll's margin of error, which means that the poll is not an outlier.
Comparison to the combined PollyVote
The current PollyVote expects Clinton to gain 64.1% of the two-party vote in Massachusetts. This means that the PollyVote is 1.8 points below her polling numbers. The PollyVote forecast is thus within the poll's margin of error.
