Dennis McKinney

Despite heavy involvement in politics, McKinney continued his career in farming and ranching through 2017.

McKinney announced his candidacy to seek the Democratic party's nomination for Kansas's 4th congressional district in the 2017 special election to fill the vacancy left by the departure of new CIA Director Mike Pompeo. The seat, in a strongly Republican district, had not been won by a Democrat since popular moderate Dan Glickman narrowly lost his re-election bid for a 10th term in 1994. In the 2016 General Election, the Republican nominees for President (Trump) and Congress (Pompeo) overwhelmingly defeated the Democratic nominees (Clinton and Giroux), by two-to-one margins in the 4th District. In 2012, federally mandated redistricting resulted in the Fourth District shifting westward into more conservative Western Kansas.

McKinney faced four Democratic opponents, none of whom had been elected to public office before. The Party nominee was selected by a vote of delegates to the 4th District Democratic convention, at the Sedgwick County Courthouse Jury Room, in Wichita, on Saturday, February 11, 2017. In the first round of voting, by 39 pre-selected party delegates, McKinney and civil rights lawyer James Thompson had the most votes, but neither had the required "50% plus one vote," so they went to a final round of voting, in which Thompson defeated McKinney 21-18.

The general election was held on April 11, 2017, with Thompson facing Kansas State Treasurer Ron Estes, the Republican nominee. Estes won, 52.5 to 47.7%, in a race where the Democratic National Committee chairman Tom Perez refused to provide financial support to Thompson. The National Republican Congressional Committee substantially outspent the Democrat, James Thompson. The NRCC contributed $92,000, in part for last minute "venomous" ads supporting Estes, which without any basis, characterized Thompson as an advocate of taxpayer funded, late term abortions, and those based on gender selection. Prior to the election, it was reported that Estes had raised $459,000 to Thompson’s $292,000. Late in the race, the Kansas Democratic party finally contributed $3,000 to the Thompson campaign, but new Democratic National Committee Chair Tom Perez said his organization would not be transferring any funds to the election. Thompson lost to State Treasurer Ron Estes, McKinney's successor, but by 6.2% in a district where the incumbent, Mike Pompeo, and presidential candidate Donald Trump, won by 31% the previous November.

In 2015, at the Kansas Historical Society, McKinney, was elected to the Board of Directors of the Kansas Historical Foundation.

He also had support from labor unions representing over 40,000 workers—particularly the Wichita/Hutchinson Labor Federation of the AFL-CIO, a coalition of 30 local unions representing over 30,000 union members, in South-Central Kansas, including teachers, aviation industry workers, operating engineers, construction workers, electricians, firefighters, state employees, janitors, train operators and other occupations. Another AFL-CIO affiliate, the Building and Construction Trades Council of Central and Western Kansas—a coalition of 13 Kansas building-trades unions, respresenting over 10,000 members—also endorsed McKinney for Congress.

McKinney also criticized the state's shift from income taxes to higher sales and property taxes, while funding for schools was sharply cut—particularly criticizing state and Congressional moves towards privatizing or cutting education, describing education as "good for the economy," and workforce education as critical to the District's primary manufacturing industry: aviation.

Not all were so fortunate: Out of the roughly 1,500 residents, ten others were killed in Greensburg during the cataclysm, with more dying or found dead later, plus two more in neighboring smaller towns. The destruction caused more than half the now-homeless and traumatized population to depart; a third of the population—500 people—moved away permanently.

McKinney was appointed to the Kansas Racing and Gaming Commission in March 2011, by Governor Sam Brownback, and was listed, in January 2017, as the Vice Chair of the Commission, which oversees and regulates gambling and animal-racing in Kansas.

While working with essentially the same staff and budget as his predecessor, McKinney managed a "major increase" in the amount of state-held unclaimed property returned to Kansans. With a booth at the Kansas State Fair, McKinney outreached taxpayers to familiarize them with the office role in locating unclaimed property. In 2010, his staff helped about 1,000 Fair attendees to recover $201,397 that was due to them which was being held in trust by the state.

Following the sudden 2010 resignation of Greensburg City Manager Steve Hewitt, who had guided Greensburg through its tornado-disaster recovery, McKinney accepted, for three months, the job of interim City Manager, until a replacement could be found. McKinney's focus was on continuing the massive recovery from one of the nation's worst tornado disasters, which had destroyed the entire town—emphasizing continuing support for Greenburg's nationally noted energy-efficient, environmentally-sensitive "green" renovation.

He resigned in 2008 to accept a gubernatorial appointment as State Treasurer, and was replaced in the Kansas House of Representatives by Pat Maloney of Kingman, Kansas.

On November 18, 2008 Governor Kathleen Sebelius appointed McKinney Kansas State Treasurer to replace outgoing Treasurer Lynn Jenkins, who had been elected to Congress representing the 2nd Kansas District. McKinney resigned from his legislative post in order to assume duties as Treasurer on January 5, 2009.

On the evening of May 4, 2007, the first of a series of powerful storms and one of the strongest tornadoes of the century, an EF5 tornado with a 1.7-mile-swath, and winds exceeding 200 miles per hour (320 km/h), flattened 95% of McKinney's hometown of Greensburg, Kansas.

He was elected by fellow Democrats as the Minority Leader in that body, leading the House Democrats from January 2003 until his resignation from the Legislature in December 2008. As Leader, he served on Legislature leadership councils, including the State Finance Council, the Calendar and Printing Committee, the Interstate Cooperation Committee and the Legislative Coordinating Council. He also directed organizing activities of the minority caucus, and streamlined legislative business, and worked across party lines successfully.

After being appointed to a vacancy in his district's seat in the Kansas House of Representatives in May 1992, he was subsequently re-elected to the seat for nine more terms. His 116th Kanss House District covers a large portion of rural south central Kansas, including Kiowa county, Barber County, Comanche County, Kingman County, northern Harper County, and southeastern Ford County.

From January 1989 through May 1992, prior to serving in the Kansas Legislature, McKinney was a Kiowa County Commissioner.

Dennis McKinney (born July 24, 1960) is a former Kansas State Treasurer. He was a member of the Kansas House of Representatives where he represented the 116th House District for ten terms, the last six as the Democratic Party's leader (Minority Leader) in the Kansas House. In January 2017, he was a Democratic candidate for the party's nomination as the 4th District of Kansas nominee in the U.S. House of Representatives. At the Democrats' 4th District nominating convention February 10, 2017, he narrowly lost to James Thompson.
