LISBON, Ohio (AP) — U.S. Senate challenger Ted Strickland is making a two-day swing through eastern and southern Ohio in the wake of losing a critical coal mine union’s endorsement.

The former Ohio governor plans stops in Struthers, Lisbon, Martins Ferry and Marietta on Wednesday. Thursday stops have not yet been released.

The Democrat is expected to remind voters in the union-heavy region of his pro-labor record as he seeks to unseat Republican Rob Portman. Portman landed the endorsement last week of the United Mine Workers of America’s National Council of Coal Miners PAC. COMPAC backed both Strickland’s runs for governor.

In tandem with the planned visits, the Strickland campaign launched what it’s calling an Appalachian regional website Tuesday. The site focuses on Portman not growing up in the region.
