Two groups say they have had enough of term limits for legislators in Arkansas. The state Chamber of Commerce-Associated Industries of Arkansas is organizing groups representing wide-ranging public and private interests to back a legislative proposal to change Amendment 73. Passed by voters in 1992, Amendment 73 limits state representatives to three two-year terms and state senators to two four-year terms. Proposed Amendment One, referred by the Legislature to the November general election ballot, would allow House members to serve six two-year terms and allow state senators to serve three four-year terms. Chamber President Ron Russell says his group will work to pass the measure. The Arkansas Farm Bureau says it will support the measure, too. Critics say the term-limits rule forces out legislators just as they have learned the legislative process.
