KANSAS CITY, Kan. (AP) — New Jersey Governor Chris Christie is lending Sam Brownback support in the Kansas governor's tougher-than-expected race against Democrat Paul Davis. Speaking Wednesday at Oklahoma Joe's Kansas City Bar-B-Que in Kansas City, Kansas, the Republican Governors Association Chairman praised Brownback as a leader. Christie said Brownback took on difficult issues, including reforming the public employee pension system. He said he never expected Kansas to be an easy win for Brownback, noting that the state previously elected Democrat Kathleen Sebelius as governor. Christie called Kansas voters "independent thinkers." Brownback used the campaign stop to talk about job creation and criticize Davis as an "Obama Democrat." Christie also was stopping at a private campaign event in Mission Hills and later in the day in Oklahoma City with Oklahoma Governor Mary Fallin.
