More than 100 nights of riots and other political unrest in Portland, Ore., appear to be having an effect on voters’ confidence in the mayor’s job performance, according to a new poll.

Mayor Ted Wheeler is viewed negatively by 63% — or nearly two-thirds – of the city’s voters, according to a poll paid for by Yes for Real Community Oversight of Police, a political action committee, OregonLive.com reported.

Only 26% of voters viewed the mayor favorably, the poll results said.

Wheeler, 58, has been the city’s mayor since January 2017. He previously served as Oregon’s state treasurer and as chairman of the Multnomah County Commission.
