Manchester Mayor Ted Gatsas and challenger Alderman Patrick Arnold will off face in their first debate Wednesday morning.
The Greater Manchester Chamber of Commerce is hosting the debate at the New Hampshire Institute of Politics at Saint Anselm College.
Gatsas and Arnold took the top two spots in the primary last month, and will face off in a November 5 election.
The debate is expected to cover topics such as education, crime and economic development.
Gatsas, a Republican, is seeking his third, two-year term as mayor.
Arnold, a Democrat, took a surprising 41 percent of the vote in the primary, placing second behind Gatsas.
Wednesday’s debate starts at 8.
Chamber President and CEO Robin Comstock will moderate.
