Kansas Republicans let their party split ruin their chances to elect a governor in 2002 and 2006. Every few days bring another reason to think they've learned their lesson for 2010, also bringing Sen. Sam Brownback, R-Kan., closer to his goal of becoming governor. His campaign committees include the biggest GOP names in the state. On Monday Kansas Insurance Commissioner Sandy Praeger, a moderate Republican, endorsed the conservative Brownback, saying, "Sam will work diligently to promote job growth and high-quality education, the cornerstones of a vibrant Kansas economy." And Thursday Brownback holds a public event with Secretary of State Ron Thornburgh, who recently scrapped his own gubernatorial bid, that has people speculating about a possible Brownback-Thornburgh ticket.
