On February 6, 2017, Clements was appointed by Governor Pete Ricketts[3] to the Nebraska Legislature replacing Bill Kintner who resigned. He is involved with the Republican Party.[4][5]
As of 2025, Clements serves as the Chair for the Appropriations Committee, a member of the Nebraska Retirement Committee, Reference Committee, Building Maintenance, Legislative Oversight Committee, and Legislature Planning Committee. He also serves as an ex-offico member on the Executive Board.[6][1][7]
District 2 of Nebraska's Legislative District serves the entirety of Cass County.[8]
Clements is pro-life and against abortion rights.[9] He has listed pro-life legislation as one of his top three priorities in the Nebraska Unicameral.[10]
Clements became a leading state election denier by embracing "the Big Lie" (President Trump's false claims of a stolen election) following the 2020 presidential contest by insisting Donald Trump actually won. Clements signed a public letter demanding a "forensic audit of every state election" similar to the fruitless 2021 Maricopa County presidential ballot audit.[11][12] That same year, he joined a fringe right-wing group, the Nebraska Freedom Coalition, in asking for a state-backed effort to audit the 2020 Nebraska election results, specifically in Douglas and Sarpy counties, despite no evidence of fraud.[13][14] Clements claimed that he was baffled how both Democrat Joe Biden and Republican Rep. Don Bacon could win in Nebraska's 2nd Congressional District, despite the fact the district experienced a similar split in 2008.[11][12]
In August 2025, Nebraska Governor Jim Pillen announced that McCook, Nebraska would become the new site of a federal immigration facility, similar to that of Alligator Alcatraz in Florida. Clements rallied his support of the facility stating "I’m supportive of the president [Trump] enforcing the law."[15]
Clements voted to pass Legislative Bill (LB) 873, Change provisions relating to corporate and individual income taxes, taxation of social security benefits, and property tax credits, which was introduced by Senator Friesen. The bill passed and will go into effect over five years, reducing personal and corporate taxes.[16][17]
Clements supports measures for affordable housing and rural workforce housing programs.[10]
Clements has stated he believes the current prison is “beyond repair, needing replaced. A new prison would have more capacity, increase programming classes, and more counseling treatment to help inmates qualify for parole sooner.”[10]
Clements supports using an I.D. to vote and a shorter amount of time for voting by mail.[10]
