Political career
Walker comes from a family background in politics. His uncle, Ronald M. Belt, was a member of the Missouri General Assembly from the 1950s through the early 1970s before becoming a judge. The young Walker attended pie suppers and other political events supporting his uncle while still a babe in his mothers arms. His maternal and paternal grandfathers were also involved in politics—one a Democrat the other Republican—and held various local elected positions on city council, county commission, and school board. Walker counts both Democrats and Republicans as political figures he looked up to and admires, notably fellow Missourians Harry S. Truman and Jerry Litton, and Conservative icon Ronald Reagan. After earning his degrees from the University of Missouri, Walker worked as a research analyst for the Missouri House of Representatives. Walker's first attempt at elected office was not successful, as he ran for the Missouri House 12th district in 1978, losing to incumbent Democrat R. L. "Scoop" Usher. Walker again faced off against Usher in 1980 and won his first term as a state representative from the 12th District, a district that held all or parts of Knox. Linn, Macon and Shelby counties. Walker ran unopposed in November 1982 to retain his seat in the House. It was during this second term, in 1983, that Walker was elected Minority Whip for the Missouri House. While in the Missouri House Walker served on the Appropriations-Social Service/Corrections, Agri-Business, Higher Education, and Tourism Committees. In 1984 Nate Walker chose not to run for the 12th District House seat, instead seeking statewide office as Missouri Lieutenant Governor. Three other Republicans also filed for the office, and in the August primary Walker finished in second place behind Mel Hancock.
2012 election
Walker had originally intended to run for a position as 1st district Adair County Commissioner in the 2012 election. However, the unexpected withdrawal of Representative Zachary Wyatt from the state representative race altered Walker's plans. He ran unopposed in the August Republican primary. In the November general election, he faced three-term former state representative Rebecca McClanahan, a Democrat whom Wyatt had defeated in November 2012. Walker defeated McClanahan by slightly over 2,000 votes, receiving 57.4 percent of the total cast.
Issue Development Standing Committee on Workers Freedom
During the Assembly's first session, Walker was the primary sponsor on two pieces of legislation in the House. He was also co-sponsor on a large number of other bills. At the conclusion of the session, Walker was honored by his fellow House members for his work on education issues by being selected "Freshman Legislator of the Year award for Education Issues".
