HARRISBURG (AP) — Pennsylvania state senator and waste-hauling millionaire Scott Wagner is the winner of the Republican nomination to challenge Democratic Gov. Tom Wolf.

Wagner’s victory in Tuesday’s three-way primary election caps a personal spending spree of more than $10 million that helped make him the front-runner and the GOP’s endorsed candidate.

Wagner defeated first-time candidates Paul Mango and Laura Ellsworth, surviving weeks of Mango’s sharp-elbowed attack ads that painted Wagner as sleazy and greedy.

Wagner fashions himself as a garbage man coming to clean up a state government that chokes the economy with regulations and taxes. He has compiled one of the Senate’s most conservative voting records.

Wolf leads a unified Democratic Party into the fall. Wagner and Wolf live in York County.
