Political career
Naughton surprised many by unseating party colleague John Mulholland at the 2009 local elections in the city's west electoral area. John Cunningham suggested that personal networking, effective postering, and the endorsement of Maureen Egan aided her victory. After her election, she was a director on Galway City Partnership Board and a member of Galway City Council's Transport Strategic Policy Committee and the Galway City Vocational Education Committee. Naughton ran unsuccessfully for the Dáil at the 2011 general election in Galway West. During the campaign in January, she alleged that councillors had been "doing the bidding" of a "hidden elite" for 20 years. In June, she was Fine Gael's choice for Mayor of Galway for 2011–12, part of a pact rotating the post between Fine Gael, Labour Party, and some Independent members. Her nomination was in doubt after Councillors objected to her allegation the previous January. She unreservedly withdrew the comments before the mayoral vote was taken. She caused controversy when she used her casting vote as Mayor to deny David Norristhe right to address Galway City Council during his campaign to get a nomination for the 2011 presidential election. She later claimed it was a "misunderstanding". At the 2011 general election, Naughton was one of four Fine Gael candidates for the five seats in Galway West; Seán Kyne and Brian Walsh were elected, while Naughton and Fidelma Healy Eames were unsuccessful. In July 2013, Walsh was expelled from the Fine Gael parliamentary party for voting against the party whip on the Protection of Life During Pregnancy Bill 2013. Healy Eames was expelled a week after Walsh for opposing the same bill in the Seanad. On 19 July, Naughton was appointed to the Seanad. Walsh was readmitted into the Fine Gael parliamentary party in 2014 but due to health reasons, he stood down before the general election. At the 2016 general election, Naughton was elected to the Dáil along with Seán Kyne. In October 2019 she was appointed to the chair of the Dáil committee investigating ethics complaints about members who voted on behalf of colleagues. She was later forced to resign after it came to light that she had done the same on several occasions. Voting on behalf of colleagues in the Dáil was not permitted. At the 2020 general election, Naughton was re-elected to the Dáil, as the sole Fine Gael TD in the five-seat constituency.
