Western NE University released the results of a new poll, in which respondents from Massachusetts were asked for whom they will vote: Republican Donald Trump or Democrat Hillary Clinton.
Western NE University poll results
The results show that 65.0% of interviewees are going to cast a ballot for former First Lady Hillary Clinton, whereas 30.0% are going to vote for billionaire Donald Trump.
The poll was conducted from September 24 to October 3 among 403 likely voters. If one takes into account the poll's error margin of +/-5.0 percentage points, the gap in voter support is statistically significant.
Putting the results in context
Single polls should be treated with caution, since they can incorporate large biases. At the very least, one should check how a poll's results compare to benchmark forecasts.
To make the results comparable to benchmark forecasts, you can convert them into two-party vote shares. This procedure yields values of 68.4% for Clinton and 31.6% for Trump.
Comparison to other polls
Looking at an average of Massachusetts polls, Clinton's current two-party vote share is at 63.5%. Compared to her numbers in the Western NE University poll Clinton's poll average is 4.9 percentage points lower. This difference is within the poll's sampling error, which suggests that the poll is not an outlier.
Comparison to the combined PollyVote
The current PollyVote anticipates Clinton to gain 63.1% of the two-party vote in Massachusetts. This means that Polly's combined forecast is 5.3 points below her polling numbers. The PollyVote forecast is therefore outside the poll's sampling error.
