The latest Vancouver election poll from Mainstreet Research shows that 41.8 percent of voters have not yet decided who they want as their next mayor.

Leading the pack, however, is NDP MP Kennedy Stewart, with 14.4 percent. He's running as an independent.

He's followed by the NPA's Ken Sim at 7.5 percent and Yes Vancouver's Hector Bremner at 7.4 percent.

Rounding out the field are Vision Vancouver's Ian Campbell at 5.3 percent, independent Shauna Sylvester at 4.5 percent, Coalition Vancouver's Wai Young at 4.5 percent, ProVancouver's David Chen at 3.7 percent, and "Maya Richards" at 1.1 percent.

One declared candidate, Fred Harding of Vancouver First, was not listed, though 9.8 percent of respondents said they were planning to vote for "someone else".

That wasn't the only oddity.

Mainstreet also asked voters which parties they intend to support, but left COPE, the Greens, and OneCity off the list. But ProVancouver, Coalition Vancouver, and Vancouver First were included, even though their support is likely less than the other three parties.

The election will take place on October 20.

Among decided and leaning voters, Stewart has 23.3 percent support, followed by Bremner at 13.6 percent and Sim at 12.4 percent. Campbell is at 9 percent, Sylvester stands at 8.2 percent, Chen comes in at 7.6 percent, and Young has 6.7 percent.

According to the pollster, 38 percent of respondents cited housing as their principal concern.

"The message here is clear: a viable mayoral candidate must have a well-thought-out affordable housing plan," Mainstreet Research CEO Quito Maggi said in a news release. "Vancouver residents feel that it is a crisis and thus expect leadership."

The company polled 862 Vancouver residents and the results have a margin of error of plus or minus 3.34 percent, 19 times out of 20.
