Southern Illinois voters overwhelmingly support a variety of reform measures they think may improve Illinois government and politics, according to a new poll by the Paul Simon Public Policy Institute at Southern Illinois University Carbondale.  From term limits and open primaries to campaign contribution limits and redistricting, the poll showed there is broad support for changes to Illinois’ political processes.  The poll of registered voters in 18 counties south of Interstate 64 was taken late September through early October.  The survey was based on a random sample of 403 registered voters who responded to telephone interviews.  The poll has a margin of error of plus or minus 4.9 percentage points.  According to the poll, 74.7 percent favored or strongly favored limiting state representatives to five terms and state senators to three terms.  A total of 73.2 percent agreed or strongly agreed that term limits made politicians more responsive to their constituents.  There were 54.8 percent either disagreed or strongly disagreed while 34.2 percent agreed or strongly agreed with the statement “term limits force legislators out of office, even if their constituents want to keep them, thereby giving more power to lobbyists and unelected staff.”  A closely related question asked about term limits for those who hold leadership positions in the General Assembly.  Here the approval levels were even higher with 83.1 percent supporting term limits for legislative leaders and 13.4 percent opposed.
