On Wednesday, Republican Gov. Charlie Baker and his Democratic challenger, former state Secretary of Administration and Finance Jay Gonzalez, will square off in the second of three scheduled debates.

The hour-long session in Boston will air live on WGBH-TV and WGBH-FM, along with public TV station WGBY in Springfield.

Baker and Gonzalez sparred on issues including transportation, taxes and the state police overtime scandal during their first debate last Tuesday.
