HARRISBURG - Pennsylvania Gov. Tom Corbett says he will soon be putting up a new round of television advertisements, with about four months to go before voters will decide whether he deserves a second term.

The Republican incumbent discussed his race against Democrat Tom Wolf in an hour-long interview this week with The Associated Press. He called his opponent "a totally unproven commodity" and defended his own record since taking office in early 2011.

Corbett says he knows Wolf only slightly from "riding the elevator together" when Wolf was revenue secretary under former Democratic Gov. Ed Rendell.

He says he plans to go after Wolf on tax issues and a lack of experience.

Through a spokesman, Wolf notes his experience includes 25 years as chief executive of a kitchen cabinet distribution company.
