Former Kansas Lt. Gov. Gary Sherrer is comparing Democratic gubernatorial candidate Paul Davis to former Republican Gov. Bill Graves.

The Davis campaign announced Monday that Sherrer would serve as one of its two senior economic advisers. Sherrer is a lifelong Republican who served as lieutenant governor under Graves from 1996 to 2003.

Graves served two terms as governor from 1995 to 2003.

Sherrer said Davis will approach economic policy calmly and responsibly. Sherrer was critical of the personal income tax cuts championed by Republican Gov. Sam Brownback.

Brownback has said the income tax cuts are boosting the economy.

The Davis campaign’s other senior economic adviser is former Lt. Gov. John Moore, who served as a Democrat with Gov. Kathleen Sebelius from 2003 to 2007.
