Boston Globe/Suffolk released the results of a new poll, in which respondents from Massachusetts were asked for whom they will vote: Hillary Clinton or Donald Trump.
Boston Globe/Suffolk poll results
The results show that 57.0% of interviewees will cast a ballot for former First Lady Hillary Clinton, while 25.0% are going to vote for businessman Donald Trump.
The poll was carried out from October 24 to October 26 among 500 likely voters. If one accounts for the poll's error margin of +/-4.4 percentage points, the difference in voter support is statistically significant.
Putting the results in context
Single polls should be regarded with caution, because they can contain large errors. Rather, one should check how a poll's results compare to benchmark forecasts.
To make the results comparable to forecasts from other methods, you can translate them into shares of the two-party vote. This procedure results in values of 69.5% for Clinton and 30.5% for Trump.
Results vs. other polls
An average of recent polls in Massachusetts sees Clinton at 67.5% of the two-party vote. This value is 2 percentage points lower than her corresponding numbers in the Boston Globe/Suffolk poll. This deviation is within the poll's margin of error, which means that the poll is not an outlier.
Results compared to the combined PollyVote forecast
The current PollyVote anticipates Clinton to gain 65.6% of the two-party vote in Massachusetts. This means that the combined PollyVote is 3.9 points below her polling numbers. Again, a look at the poll's margin of error shows that this difference is negligible.
