INDIANAPOLIS — A campaign debate between the Republican, Democratic and Libertarian candidates for governor of Indiana is underway.

Democrat John Gregg, Republican Eric Holcomb and Libertarian Rex Bell were meeting Monday evening at the University of Indianapolis for their second of three debates.

The televised event is expected to last an hour.

Holcomb, the current lieutenant governor, and former Indiana House Speaker Gregg didn’t confront each other much during an initial debate last week on education issues before an Indianapolis audience consisting mostly of high school students. Gregg blamed Republican-backed school initiatives for Indiana’s teacher shortages, while Holcomb argued the state isn’t alone in struggling to attract would-be educators.

One more debate scheduled for Oct. 25 at the University of Southern Indiana in Evansville.
