Indiana Gov. Frank O’Bannon suffered a cerebral hemorrhage in his Chicago hotel room Monday morning, and underwent emergency surgery at Northwestern Memorial Hospital in Chicago. At NUVO’s press time Tuesday morning, the governor’s prognosis was uncertain. Lt. Gov. Joe Kernan assumed the responsibility of acting governor Monday afternoon under what Kernan called “a common sense provision” of the Indiana Constitution. The formal process for appointing an acting governor, spelled out elsewhere in the state’s Constitution, has not yet been invoked. The 73-year-old O’Bannon was in Chicago to attend the U.S. Midwest-Japan Conference. O’Bannon’s statewide popularity allowed him to win comfortable victories over highly touted Republican opponents Stephen Goldsmith in 1996 and David McIntosh in 2000. Like most U.S. governors in recent years, O’Bannon has struggled with a significant state budget crunch, but the Corydon newspaper publisher and longtime state senator has retained a high level of personal affection and respect from elected officials and activists in both parties.
