Results of a new poll carried out by NBC-WSJ-Marist were released on April 12. Participants from Illinois were asked, who they would give their vote to, if the election were today. Of those who answered the question, 57.0% said that they are going to vote for the Democrats, whereas 32.0% said that they would give their vote to the Republicans. This poll was conducted from March 4 to March 10, among a random sample of 1968 registered voters.
Translating these results into two-party vote shares yields values of 64.0% for the democrat Clinton and 36.0% for Trump.
