Republican congressional candidate Samuel "Joe the Plumber" Wurzelbacher has sunk plans for a congressional candidate's debate Thursday at

with Toledo Democratic Rep. Marcy Kaptur.

Wurzelbacher says the City Club debate "just didn't work in with the schedule," but he's got two other public events with Kaptur in the pipeline.

The candidate, who first gained public exposure by questioning President Barack Obama at a 2008 Toledo-area campaign event, said he plans to attend an Oct. 26 debate in Toledo hosted by WTVG Channel 13 and The Blade newspaper, as well as an

in Lorain hosted by the Coalition for Hispanic/Latino Issues and Progress.

Wurzelbacher says his door-to-door campaigning in the Cleveland area is giving him ample exposure to voters in the Cuyahoga County portion of the newly configured congressional district, which stretches from Cleveland to Toledo along Lake Erie.

City Club spokeswoman Carrie Miller said Wurzelbacher did not respond to her organization's debate invitation, so Kaptur will speak at the event by herself.
