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. According to the results, 46.0% of respondents are going to vote for the Democrats, while 38.0% are going to vote for the Republicans. The poll was carried out from October 25 to October 31 among 600 likely voters. The margin of error is +/-4.0 percentage points.
Converting these results into two-party vote shares yields values of 54.8% for the Democrats and 45.2% for the Republicans.
