The results of a new poll, conducted on behalf of NBC-WSJ-Marist in Michigan, were released on March 30. In the survey participants were asked, whether they would vote for democrat Hillary Clinton or republican Donald Trump, assuming that these two candidates would win the primaries. Of those who responded, 52.0% revealed that they plan to vote for the Democrats, whereas 36.0% revealed that they would give their vote to the Republicans. This poll was conducted from March 1 to March 3, among a random sample of 2229 registered voters. Results have a +/-2.1 percentage points error margin.
Translating these results into two-party vote shares yields figures of 59.1% for the democrat Hillary Clinton and 40.9% for the republican Donald Trump.
