She was appointed to the Durham County Women's Commission by the county board of commissioners in 1987, and later became its chair. During the 1990 senatorial election she was county coordinator for Harvey Gantt's campaign in Durham County. She worked for his campaign during the 1996 election.

State legislature
During Lewis' tenure in the state house she served on the Public Health Care and Human Services committee and as vice-chair of the State,Veterans and Military Affairs committee. She was a member of the LGBTQ Caucus.
Lewis refused to sign off her aide's time card in December 2023,and Senate President Steve Fenberg had to sign it instead. Fenberg warned Lewis about her poor behavior to her staffers and later stated that they would not help her vet or place new aides for her in the upcoming legislative session. She was removed as chair of the Local Government and House committee in January 2024,and her sponsorship was removed from legislation to prevent wage theft in the construction industry. Lewis denied the allegations made against her. On December 3,she was barred from having state-paid aides after a misconduct complaint was filed about her using staffers to do yard work and bartend.
On February 18,2025,Lewis announced on Facebook at 6 A.M. GMT that she had resigned,with it having gone in effect the previous day at 7:15 P.M. GMT. Resigning from the state legislature ended the ethics probe against her. Two hours later the Senate Ethics Committee reported that Lewis had submitted at least one fabricated letter of support sent to the panel,claiming that it was from Anna McLean,a former aide. Lewis claimed that the letter was supposed to be information she gathered from conversations with McLean,despite it being in the first person and using her name on the letterhead,and that it was accidentally submitted. Another aide,Tara Mastracchio,also said that the letter submitted by Lewis with her name attached was not written by her.
The district attorneys' offices in Denver and Boulder are investigating Lewis for using deceit in an attempt to influence a public servant and signature forgeries. On July 6,2025,the Denver District Attorney's Office charged Lewis with the felony offense of attempting to influence a public servant. The charge can result in a $500,000 fine or up to six years in prison.
