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
The results show that 60.0% of participants said that they would cast a ballot for former First Lady 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. The error margin is +/-4.4 percentage points, which means that the levels of voter support for the Democratic and the Republican candidate differ significantly.
Putting the results in context
Individual polls should be regarded with caution, as they often contain large errors. Instead of relying on results from single polls, one should consult combined polls or, even better, the combined PollyVote forecast that draws upon different methods and data.
To make the results comparable to benchmark forecasts, we convert them into two-party vote shares. This procedure results in figures of 65.9% for Clinton and 34.1% for Trump.
Results vs. other polls
An average of recent polls in Massachusetts has Clinton at 63.2% of the two-party vote. Compared to her numbers in the WBUR/MassINC poll Clinton's poll average is 2.7 percentage points lower. This margin is within the poll's sampling error, which suggests that the poll is not an outlier.
Results compared to the combined PollyVote prediction
The most recent PollyVote expects Clinton to gain 63.9% of the two-party vote in Massachusetts. This means that the PollyVote forecast is 2.0 points below her polling numbers. Again, a look at the poll's error margin reveals that this deviation is negligible.
