Jason Fields

In 2020, Fields announced he would run for election as Milwaukee City Comptroller. He topped the field in the February primary election, taking 43% of the vote, but was narrowly defeated in the general election by deputy comptroller Aycha Sawa. Fields made an issue of Sawa's handling of an audit of lead piping which was rated as exaggerrated and misleading. The comptroller election was one of several Wisconsin elections significantly impacted by the 2020 COVID-19 pandemic in Wisconsin.

On May 12, 2020, Fields filed paperwork with the Wisconsin Elections Commission declaring he would not be a candidate for re-election in 2020. He also released a press release confirming the decision, stating, "After much consideration about the future, and conversations with my dear wife, La Tasha Fields, I have decided to not seek re-election to the Wisconsin State Assembly, District 11."

In 2016, Barnes announced he would challenge incumbent Lena Taylor in a Democratic primary for her seat in the Wisconsin State Senate. This left an opening in the 11th Assembly District, and Fields decided to run again for his old seat. He defeated Milwaukee community organizer Darrol D. Gibson in the Democratic primary and was unopposed in the general election.

In 2012, he lost his bid for reelection in the Democratic primary, losing to Mandela Barnes, son of a public school teacher, who had made major issues of Fields' support for the school voucher program, and Fields’ opposition to limiting interest rates charged by payday loan companies whose charges can exceed a 500% annual percentage rate. (Fields' brother Jarett, who was a candidate for the Democratic nomination in the nearby 19th District, was also defeated.) Fields was one of two veteran Milwaukee-area Democratic incumbents (the other being Peggy Krusick) to be unseated in that August primary by challengers who argued that the incumbent was too conservative to represent the district properly.

Fields, who had served as Fourth Congressional District Chairman of the Wisconsin Democratic Party and held other party office, was first elected to the Assembly in 2004, and was thrice reelected from 2006-2010). His committee assignments included those on financial institutions (which he chaired during the 2009-2011 session); insurance; jobs, economy and small business, education reform; transportation; ways and means, workforce development, economic development; and urban and local affairs.

Jason M. Fields (born January 29, 1974) is an American politician, and a former stockbroker, financial advisor, and banker from Milwaukee, Wisconsin. He is a Democratic member of the Wisconsin State Assembly, representing the 11th Assembly District since 2017. Fields previously represented this district from 2005 to 2013. Fields lost his seat to Mandela Barnes, who defeated him in the 2012 Democratic primary, but was able to reclaim it when Barnes ran for election to the Wisconsin State Senate in 2016. Fields ran for Milwaukee City Comptroller, the city's top financial job, in the 2020 spring election, but lost narrowly. On May 12, 2020, he filed paperwork indicating he would not run for re-election in 2020.

Fields was born in Milwaukee on January 29, 1974, and graduated from Milwaukee Lutheran High School in 1992. He worked as a stockbroker, financial advisor, and banker, and is a certified financial education instructor. He returned to school as an adult, earning his Bachelor's degree in Business Management from Milwaukee's Cardinal Stritch University in 2014. He is a member of the Prince Hall Masons, the Alpha Phi Alpha fraternity, the Independent Order of Odd Fellows, the Elks Lodge of Milwaukee #46, and the International Society of Business Leaders.
