An early poll for Detroit's 2017 mayoral election next fall shows Mayor Mike Duggan with a wide early lead over challenger Coleman Young II.

The poll, which offered respondents a choice between those two candidates, found Duggan with support of 46 percent of likely voters and Young with 21 percent; 29 percent said they were "unsure" and 4 percent said they supported another candidate, according to a news release from MIRS Newsletter, which commissioned the poll.

The poll of 310 likely voters, conducted by Denno Research, had a margin of error of 6 percent.
