Florida House of Representatives
In 2010, when incumbent Republican State Representative Tom Grady declined to seek another term in the legislature, Passidomo ran to succeed him in the 76th District, which stretched from Naples Park to Chokoloskee on the western coast of Collier County. She won both the Republican primary and the general election entirely unopposed.

Following the reconfiguration of legislative districts in 2012, Passidomo was moved into the 106th District, which included most of the territory that she had previously represented in Collier County. In the Republican primary, she was opposed by David Bolduc, whom she easily defeated with 73% of the vote. Advancing to the general election, Passidomo faced Libertarian candidate Peter Richter, whom she defeated in a landslide, winning her second term in the legislature with 79% of the vote.

Florida Senate
In 2016, Passidomo ran for the Florida Senate District 28 seat vacated by Garrett Richter, who was term limited. She defeated state representative Matt Hudson in the Republican primary, 58% to 42%, and faced only write-in candidates in the general election.

Passidomo was re-elected to a second term on November 6, 2018, after facing no primary challenger and winning 65% of the vote in the general election.

Passidomo is one of the founders of Maggie's List.

In 2020 she was an elector for Donald Trump.

In 2021, Passidomo was elected by her colleagues to preside over the upper chamber of the Florida Legislature during the 2022-2024 legislative term. She is the third woman in the 185-year history of the Florida Senate to serve as President.
