NBC-WSJ-Marist published the results of a new poll. In this poll, interviewees from Illinois were asked for whom they will vote: Democrat Hillary Clinton or Republican Donald Trump.
NBC-WSJ-Marist poll results
Of those who answered the question, 57.0% said that they plan to vote for former New York Senator Hillary Clinton, whereas 32.0% revealed that they would give their vote to real estate developer Donald Trump.
This poll was conducted from March 4 to March 10, among a random sample of 1968 registered voters.
Putting the results in context
Single polls often include substantial biases, and should be interpreted with caution. Instead of trusting the results from single polls, the evidence-based approach is to look at combined polls or, even better, the combined PollyVote forecast that uses forecasts from different methods, each of which uses different data.
In order to make the results comparable to benchmark forecasts, one can translate them into shares of the two-party vote. The corresponding figures are 64.0% for Clinton and 36.0% for Trump.
Results compared to the combined PollyVote forecast
The most recent PollyVote forecasts Clinton to gain 58.2% of the two-party vote in Illinois. That is, Polly's prediction is 5.8 points below her polling numbers.
