Carter ran for and was elected to the Arkansas House of Representatives in 2008 to represent the Cabot area of Lonoke County. He beat an intraparty rival in the Republican primary and was unopposed in the November election. He was selected to be Chairman of the Revenue and Taxation Committee during his second term and he served as Speaker of the House from 2013 to 2015. In the Republican primary held on May 20, 2014, Tim Lemons, with 1,728 votes defeated intraparty rival Darlene Byrd, who polled 1,091 votes, for the party's nomination to succeed Carter. Lemons then prevailed in the November 4general election.
Chairman of the House Revenue and Taxation Committee
Carter served as Chairman of the Revenue and Taxation Committee during his second term. As Chairman, he held hearings to start the discussion of tax reform in Arkansas, during which he advocated for lower tax rates on families and businesses. “A working-class family with an annual income in the low $30,000 range is in the highest marginal tax bracket in Arkansas, even though that family’s income exceeds the federal poverty level by only $10,000 or so,” Carter said. “This needs to be addressed along with other tax ‘loopholes’ and how competitive we are with our surrounding states. Essentially, I’d like to see a broader base with lower rates across the board.”
Speaker of the House
Carter is the first Republican Speaker since Reconstruction. He won on a secret vote of fifty-two to forty-five against a more moderate fellow Republican, Terry Rice of Waldron in Scott County. Carter received a score of 89 from the Advance Arkansas Institute on issues of smaller government, individual freedom and lower taxes, ranking among the 10 most conservative members of the House. Carter depended on bipartisan support to win because his party controls only fifty-one of the one hundred House seats. Carter was known for his good working relationship with former Democratic GovernorMike Beebe and had been mentioned as a Republican candidate to succeed Beebe in 2014. However, he declined to run for governor and instead endorsed the party's unsuccessful 2006 nominee for the post, former U.S. Representative Asa Hutchinson, who is also a former United States Secretary of Homeland Security. Hutchinson lost to Beebe by a wide margin in a heavily Democratic year but rebounded to win the governorship in 2014.
