Robert Lewis Cowles III (born July 31, 1950) is a retired AmericanRepublican politician fromGreen Bay, Wisconsin. He served 38 years as a member of theWisconsin Senate, representingWisconsin's 2nd Senate district from 1987 to 2025. Before being elected to the Senate, he served four years in theWisconsin State Assembly (1983–1987).

Robert Cowles was born and raised and lived most of his life inGreen Bay, Wisconsin. He attended theUniversity of Wisconsin–Green Bay, earning hisbachelor's degree in math and science in 1975. After graduating, he briefly pursued hismaster's in public administration at University of Wisconsin–Green Bay, but did not complete that degree.^[1][2][3][4]

He was formerly a director of analternative energy division for a communications construction company.^[5]

Despite his parents being prominent local Republicans, Cowles became active in politics with theDemocratic Party during his college years.^[1] In 1974, he was a campaign co-chairman for unsuccessful DemocraticWisconsin State Assembly candidate Jon A. LeDuc.^[6] During the1976 Democratic Party presidential primaries he was an organizer in Wisconsin for Arizona U.S. representativeMo Udall's presidential campaign. He was also active in theUnited States Junior Chamber, and was president of the group in 1977.^[7]

In 1978, Cowles made his first bid for state elected office.^[1] He ran for Wisconsin State Assembly in what was then the4th Assembly district; in the Democratic primary, he faced the candidate he had previously worked for, Jon A. LeDuc, who was then making his third bid for election to the Assembly. Cowles and LeDuc ran on nearly identical policy platforms, both arguing for cuts to state bureaucracy and both proposing a plan for indexing the state income tax to inflation. For Wisconsin's then-surplus, they also both advocated sending the money to municipalities in shared revenue as part of a program for municipalities to cut property taxes.^[8][9] Cowles prevailed in the primary, receiving 57% of the vote, but was defeated in the general election by RepublicanGary T. Dilweg.^[10]

After losing the 1978 election, Cowles reduced his political activity and re-emerged in 1982 as aRepublican. On his party-change, he explained that he found the Republican Party better fit his conservative political philosophy.^[11]

That year, he ran for Assembly again in what was then the75th Assembly district under the 1982court-ordered redistricting plan. He faced two opponents in the Republican primary, but prevailed with 50% of the vote. He went on to defeat Democrat Joel Edler in the general election, receiving 56% of the vote.^[12] Another redistricting act was passed in 1983, Cowles ran for his second term in 1984 in what was then the6th Assembly district. He prevailed in another contested primary, and went on to defeat Democrat Gregory Kirschling in the general election.^[13][14]

While Cowles was being re-elected to the assembly in 1986, his district's state senator,Don Hanaway, was being electedAttorney General of Wisconsin. Hanaway still had two years remaining on his term in theWisconsin Senate, and therefore aspecial election was called for the spring of 1987 to fill the vacancy in the2nd Senate district. Cowles was one of four Republicans who entered the special primary to succeed Hanaway, he went on to win the primary with 41% of the vote over state representativeCathy Zeuske and former representativeWilliam J. Rogers. In the general election, he defeated DemocratRosemary Hinkfuss.^[14] Since the 1987 special election, Cowles has been re-elected nine times and survived one recall election.

In the106th Wisconsin Legislature, Cowles chairs the Senate Committee on Natural Resources and Energy; he has been chair of the Senate committee dealing with energy legislation since 2011, and also held the chair multiple times when Republicans held the majority between 1993 and 2006.^{[note 1]} He also previously served as co-chair of theJoint Committee on Audit, and he sits on the Senate Committee on Transportation and Local Government; he has sat on the committee responsible for transportation issues since 2013.^[2][3]

At the start of the100th Wisconsin Legislature, Cowles supported GovernorScott Walker's controversial "budget repair bill," which passed into law as2011 Wisconsin Act 10 after months of intense partisan controversy andprotest. Much of the controversy was caused by a provision of the law which removed the rights of public employee unions to engage in collective bargaining with state and municipal governments. The law's passage launched a state-wide effort to recall state elected officials who had supported the bill, and Cowles was one of the state senators targeted in that recall effort.

March 2, 2011, the "Committee to Recall Cowles" registered with theWisconsin Government Accountability Board.^[15] On April 28, roughly 26,000 signatures to recall Cowles were filed with the Government Accountability Board. In late May 2011, the Wisconsin Government Accountability Board verified petitions against Cowles.^[16] The recall election was held on August 9, 2011, with Cowles defeating the Democratic challenger,Nancy Nusbaum, 60 percent to 40 percent.^[17]

The 2024redistricting act substantially redrew the maps in the Green Bay area. Cowles was drawn out of his 2nd Senate district seat and into the 30th Senate district with two other incumbent Republican state senators. Cowles initially announced he would relocate to the new 2nd Senate district, but later announced that he would retire and end his 42 year legislative career.^[18]

Just before the2024 election, Cowles announced that he would vote for the Democratic Party presidential nominee,Kamala Harris, and stated that Donald Trump "has to be defeated". In announcing his decision, Cowles said, "I really think this is one of the most important things I've done... Cowles made this announcement in an episode of the Civic Media show, “Rational Revolution,” hosted by Mark Becker on October 24th 2024, Just before the Presidential Election, hoping to move the Needle. Cowles Said I believe this guy Trump is a Totalitarian and very much a Fascist,” said Cowles. The big picture that really came to me in recent days, in the last week, is thinking about thinking about fascism in World War II, and members of my own family that fought the fascists both in Japan and Germany, and all the guys that are buried all over the place of this country, in Arlington, he said. During the Radio show, Becker played a clip from Liz Cheney’s recent speech in Ripon, Wisconsin, endorsing Harris, and Cowles talked about agreeing with all of what she had to say. Hopefully, people will accept that and listen to me, those that have trusted me and believed in me will think about that, and if they're undecided, that we have to make a change here... Trump has to be defeated, and we have to protect the Constitution. And the country will go on, even with some liberal things that Harris might do, or might not do... You have to have the foundation of the Constitution, to protect democracy. If you don't have that, we will disappear."^[19]
