During his legislative career, Murphey's projects have included setting term limits on statewide elected officials, the creation of the data.ok.gov transparency portal, and the co-sponsorship of legislation to centralize of information technology systems in Oklahoma state government. During his first year in office, he authored legislation to lower legislative pay. He is also the author of unsuccessful attempts to end lobbyist gift-giving to legislators and to remove the Oklahoma Legislature's exemption from the state's open records and open meeting laws. In 2006, Jason Murphey was the only Oklahoma legislative candidate to defeat an incumbent in the 2006 primary/runoff election. In 2008, Murphey's 12,978 votes represented more votes than any other candidate for the House District 31 seat had received in the history of the district. In 2010, Murphey won re-election with more votes than any other Oklahoma State House Republican candidate that election season. Murphey's vote total was also the biggest vote tally for a Republican primary candidate in the history of House District 31. In 2014, Government Technology magazine named Murphey as one of the Tech-Savviest Legislators in the U.S. On June 24, 2014, Murphey won re-election by capturing more votes than any other Oklahoma House Republican on the ballot that day. He scored the most votes of any State House candidate and secured the highest percentage. Murphey will be required to step down in 2018 due to term limits.
Lobbyist reform
Murphey has been critical of the influence of lobbyists over state politicians. He has pledged to refuse personal gifts and campaign contributions from lobbyists and the groups that employ them. He proposed legislation that would have created a "no gift" list that legislators could use to refuse lobbyist gifts. In 2016, he proposed legislation to end all lobbyist gift-giving to legislators.
Term limits
Murphey authored a bill to let constituents vote on establishing term limits on all statewide elected officials. The voters approved the proposal in November 2010.
Openness
Murphey authored legislation to remove an exemption for the Oklahoma Legislature in the state's open meeting and open records laws. As of 2016, his attempts have been unsuccessful.
