Michael Bradley Enzi ( //; born February 1, 1944) is an American politician and accountant serving as the senior United States Senator from Wyoming, a seat he was first elected to in 1996. He is a member of the Republican Party.
Raised in Thermopolis, Wyoming, Enzi attended George Washington University and the University of Denver. He expanded his father's shoe store business in Gillette, Wyoming before being elected the city's mayor in 1974. In the late 1970s, he worked for the United States Department of the Interior. He served as a state legislator in both the Wyoming House of Representatives (1987–1991) and Wyoming Senate (1991–1997). During the 1980s and 1990s, he worked as an accountant and executive director in the energy industry.
Enzi was elected to the U.S. Senate in 1996 with 54% of the vote and was reelected in 2002 with 73% of the vote, in 2008 with 75% of the vote and in 2014 with 71% of the vote.  Since his election, he has consistently been ranked one of the most conservative members of the Senate. He was a member of the 2009 Gang of Six, which attempted to negotiate health care reform. Since 2015, he has also chaired the Senate Budget Committee, during the 114th and 115th Congresses.
Mike Enzi was born on February 1, 1944 in Bremerton, Washington, the son of Dorothy M. (née Bradley) and Elmer Jacob Enzi. His paternal grandparents were ethnic Germans from Ukraine, and his mother had Irish and German ancestry.   Enzi was raised in Thermopolis, Wyoming, after his father's return from military duty on the Pacific Coast. He attended elementary school in Thermopolis and graduated from Sheridan High School in 1962.  He is an Eagle Scout and a recipient of the Distinguished Eagle Scout Award from the Boy Scouts of America.  
Enzi received a degree in accounting from George Washington University in Washington, D.C., in 1966. He is also a member of the Sigma Chi Fraternity and Alpha Kappa Psi business fraternity. He received an M.A. in retail marketing from the University of Denver in Colorado in 1968. He also served in the Wyoming Air National Guard from 1967 to 1973.  On June 7, 1969, Enzi married the former Diana Buckley; the couple has two daughters (Amy and Emily) and a son (Brad), as well as four grandchildren (Trey, Lily Grace, Megan Riley, and Allison Quinn). 
Soon after his marriage, Enzi moved to Gillette, where he expanded his father's shoe-sale business,  NZ Shoes, which later also had locations in Sheridan and in Miles City, Montana. As a young business owner, he served as president of the Wyoming chapter of the United States Junior Chamber.
Enzi was elected mayor of Gillette in 1974 at age 30 and held the position for two terms, serving until 1982. During his tenure, the city doubled in size. From 1976 to 1979, Enzi worked with the U.S. Department of Interior on energy policy via its Coal Advisory Committee.
Enzi was elected to the Wyoming House of Representatives as a Republican and served from 1987 to 1991. He was then a member of the Wyoming Senate from 1991 to 1997. In the State Senate Enzi became a vocal opponent of proposals to legalize gambling in the state. In 1994 he served as the primary spokesman of WyBett, an anti-casino group. He also worked from 1985 to 1997 as an accountant with an oil drilling company and during the 1990s as an executive director with the Black Hills Corporation, an energy holding company that owns utilities and natural gas and coal mining operations.
Enzi was first elected to the U.S. Senate in 1996. He endured a tough primary challenge during his first campaign before winning the general election by an 8-point margin. At the time of his election, Enzi was the only accountant in the U.S. Senate.  Enzi won reelection by a large margin in 2002. He became the senior U.S. Senator from Wyoming when his colleague Craig L. Thomas died of leukemia on June 4, 2007. His new colleague is fellow Republican John Barrasso, a former State Senator from Casper, whom Enzi, as a then-State Senator himself, narrowly defeated in the 1996 senatorial primary, 32% to 30%.
In 2008 Enzi was reelected to his third term in the U.S. Senate with over 76% of the vote against Democratic opponent Chris Rothfuss, a professor of political science at the University of Wyoming. 
In July 2014 Enzi declared his intention to run for a fourth term and was reelected in November with 71% of the vote.  No incumbent Wyoming Republican Senator running for reelection in the direct vote era has failed to win his party's nomination.  In 2013, Enzi was accused of lying about his friendship with Cheney and relying on political action committee funding in preparation for his reelection campaign and a primary challenge by Liz Cheney.  The National Republican Senatorial Committee and Wyoming Republicans supported Enzi. 
In 2005 Enzi became the ninth U.S. Senator from Wyoming to ascend to the rank of Chairman on one of the 16 standing committees in the U.S. Senate. He has been a member of the Senate Health, Education, Labor and Pensions Committee since his arrival in the U.S. Senate in 1997. During his time as Chairman of the HELP Committee, 37 bills were reported out of the committee, 23 bills passed the Senate, 352 nominations were reported favorably, and 15 laws came through the committee that were signed by President George W. Bush.
Enzi supports imposing a new sales tax on internet sales and other sales of interstate commerce. On November 9, 2011 he introduced Senate Bill 1832 which would require businesses to calculate, collect and pay the new tax whenever they sell products or services to consumers from another state, regardless of the manner in which the sale is transacted. The bill provides no exemption for businesses in tax-free states, so even sellers within states that have no sales tax would be required to calculate and pay the new tax.
A strong supporter of the coal industry, Enzi also rejects alternative energy proposals and advocates Arctic National Wildlife Refuge (ANWR) and offshore drilling. Enzi's committee led the first revisions to mine safety laws in 28 years by promoting the use of new technologies to improve mine safety and save lives. He has a somewhat mixed record on trade issues: he has voted to approve most free trade bills but has rejected the Central America Free Trade Agreement (CAFTA), one of the largest pieces of such legislation, and is opposed to presidential fast-tracking of trade relation normalization. 
Enzi takes a hard-line view on illegal immigration and has been rated highly by groups that support tighter border controls. He has voted in favor of the construction of a fence along the U.S.-Mexican border and against the implementation of guest worker programs. Enzi has voted to uphold the PATRIOT Act and is opposed to calls to cut down on wiretapping and to extend rights to Guantanamo Bay detainees. Enzi also rejected calls for a timetable for military withdrawal from Iraq. 
Enzi opposed President Barack Obama's health reform legislation; he voted against the Patient Protection and Affordable Care Act in December 2009,  and he voted against the Health Care and Education Reconciliation Act of 2010. 
Enzi was one of the Gang of Six senators working to find a bipartisan solution to health care reform.  Speaking on the topic, Enzi told the media, "We all want health care reform that will reduce costs, improve quality and expand access without breaking the bank. The bipartisan talks we're having in the Finance Committee represent the best chance we have of achieving our shared goals, and I urge Democrat (sic) leaders not to close the door on these productive discussions."  In 2017, Enzi was part of the group of 13 Senators drafting the Senate version of the AHCA behind closed doors.    
Enzi was one of 22 senators to sign a letter  to President Donald Trump urging the President to have the United States withdraw from the Paris Agreement. According to the Center for Responsive Politics, Enzi has received over $270,000 from the oil and gas industry since 2012. 
Despite his strong support of the War in Iraq, he was one of 14 U.S. Senators to vote against the Iraq War funding bill in May 2007 because he opposed the clauses of the bill which increased domestic spending.
In December 2010, Enzi was one of 26 senators who voted against the ratification of New Start,  a nuclear arms reduction treaty between the United States and the Russian Federation obliging both countries to have no more than 1,550 strategic warheads and 700 launchers deployed during the next seven years, and providing for a continuation of on-site inspections that halted when START I expired the previous year. It was the first arms treaty with Russia in eight years. 
On social issues, Enzi is strongly conservative. He opposes all types of abortion and has voted in favor of proposals that would provide restrictions on the procedure for minors, those stationed on military bases, and other groups. He has voted in favor of failed constitutional amendments that suggested banning gay marriage and flag desecration. However, in August 2013, Enzi was the only Republican to sign a letter in support of ending the national ban on donated blood from men who have sex with men.  Enzi also is a strong supporter of gun rights and is ranked very favorably by the National Rifle Association (NRA). 
In April 2013, Enzi was one of 46 senators to vote against the passing of a bill which would have expanded background checks for all gun buyers. Enzi voted with 40 Republicans and 5 Democrats to stop the passage of the bill. In his blog FiveThirtyEight, statistician Nate Silver predicted a 0% chance of Enzi voting “aye” on the final bill. 
On May 4, 2019, Enzi announced that he would not seek reelection to a fifth term in the Senate.
