Officials at the Kansas Republican Party are speculating that Gov. Kathleen Sebelius, a Democrat, has been “floated” as a possible replacement for Kansas University Chancellor Robert Hemenway, who plans to step down in June.But Sebelius’ office declined to get into the speculation game. “We’ll let the speculators continue speculating. The governor learned of the chancellor’s departure in the news this week — just like the rest of us. We’ve not talked about anything beyond the thoughts she shared about Chancellor Hemenway’s service,” said Nicole Corcoran, a spokeswoman for Sebelius.On Saturday, Sebelius ended weeks of speculation about her future when she announced she did not want to be considered for a Cabinet position in President-elect Barack Obama’s administration.On Monday, Hemenway said he would leave the chancellor’s job June 30 but continue writing and teaching.The Kansas Board of Regents has said it will conduct a national search for a new chancellor.
