Opponents and proponents of a constitutional convention will meet for a debate 6:30 p.m. tonight at the Hartford Public Library, 500 Main Street, Hartford.

The question, “Shall there be a Constitutional Convention to amend or revise the Constitution of the State?” appears on the ballot every 20 years. If voters decide in favor of a convention this November the legislature will appoint delegates to debate revisions to the state constitution.

Wednesday night’s panel will include Attorney General Richard Blumenthal; Matthew M. Daly, chairman of the Constitution Convention Campaign; John Woodcock, vice chairman of the Constitution Convention Campaign; constitutional scholar Kim Knox; and Peggy Shorey, Vote No Coalition campaign manager.
