The first nonpartisan poll of the Democratic mayoral primary shows none of the five top contenders with a clear lead, with 20 percent of respondents undecided. The poll was conducted from April 21 to 25 with 1,013 likely Democratic voters, or Democrats who have already voted. The credibility interval, similar to a margin of error, was +/- 3.8 percentage points. Off-year primaries are considered difficult to poll, given the smaller number of voters and the higher prosensity of primary voters to change their mind.
