NBC-WSJ-Marist poll results
Of those who responded, 57.0% said that they intend to vote for former First Lady Hillary Clinton, while 32.0% said that they would give their vote to real estate developer Donald Trump.
The poll was carried out from March 4 to March 10 with 1968 registered voters.
Putting the results in context
Individual polls can contain large biases, which is why they should be treated with caution. Instead of relying on results from single polls, the best practice is to consult combined polls or, even better, a combined forecast that relies on forecasts from different methods, each of which draws upon different data.
To make the results comparable to forecasts from other methods, you can convert them into two-party vote shares. The corresponding figures are 64.0% for Clinton and 36.0% for Trump.
Results compared to the combined PollyVote forecast
The latest PollyVote expects Clinton to gain 58.4% of the two-party vote in Illinois. That is, Polly's combined forecast is 5.6 points below her polling numbers.
