LorasLoras published the results of a new poll. In this poll, respondents from Illinois were asked for whom they will vote: Democrat candidate Hillary Clinton or Republican candidate Donald Trump.
LorasLoras poll results
Of those who replied, 47.0% said that they will vote for former Secretary of State Hillary Clinton, whereas 33.0% revealed that they would give their vote to businessman Donald Trump.
This poll was conducted from September 13 to September 16, among a random sample of 600 likely voters. There is a sampling error of +/-4.0 percentage points. Considering this error margin, the gap between both candidates is statistically significant.
Putting the results in context
Single polls should be interpreted with caution, because they can contain large errors. Rather than trusting the results from single polls, the best practice is to rely on combined polls or, even better, a combined forecast that incorporates different methods and data.
To make the results comparable to benchmark forecasts, you can translate them into two-party vote shares. This procedure yields figures of 58.8% for Clinton and 41.3% for Trump.
Comparison to the combined PollyVote
The most recent PollyVote forecasts Clinton to gain 58.3% of the two-party vote in Illinois. Hence, the PollyVote forecast is 0.5 points below her polling numbers. The PollyVote forecast is therefore in line with the poll's sampling error.
