Kansas Insurance Commissioner Sandy Praeger is opposing Governor Brownback's re-election as governor.
Commissioner Praeger has joined a new bipartisan group hoping to thwart Brownback's bid for a second term.
Praeger went public yesterday about her break with Brownback and other Kansas Republicans.
She's appearing in an online video criticizing the governor from the Reroute the Roadmap group.
The group's six sponsors include Wichita businesswoman Jill Docking.
She's the lieutenant-governor running mate of Democratic gubernatorial candidate and Kansas House Minority Leader Paul Davis.
Kansas GOP Executive Director Clay Barker says Praeger has broken with fellow Republicans previously in supporting the federal health care overhaul.
