2009–2011 Power first sought election to public office at the
2009 local elections, contesting for Fianna Fáil in the Howth–Malahide
local electoral area of
Fingal County Council. She was unsuccessful, coming seventh with 7.5% of the vote. During this period she was employed as a political adviser by Minister
Mary Hanafin in the Departments of Tourism, Social and Family Affairs and Education on a salary reported to be €100,191 per year plus pension contribution. She remained a political adviser to Hanafin until the 2011 general election.
2011–2015 In February 2011, before the general election, Fianna Fáil Leader
Micheál Martin appointed Power directly to his Front Bench, in doing so breaking the convention that members of the Front Bench hold elected office. Power contested the
Dublin North-East constituency at the
2011 general election but was not elected. In a three-seat constituency, she polled fourth on the first count, receiving 4,794 first preference votes (11.5%). In March 2011, Micheál Martin nominated Power via the Oireachtas sub-panel to contest the 2011 Seanad election on the
Industrial and Commercial Panel. She was elected, polling 75 votes.
2015–present On 25 May 2015, Power left Fianna Fáil, citing disagreements over how they had handled the
same-sex marriage referendum. Power believed that Fianna Fáil did not sufficiently support the Yes campaign. In December 2015, Power caused controversy when it emerged she had used taxpayers money to print 73,000 calendars that were to be distributed throughout her constituency just weeks before the
2016 general election. She contested the
2016 general election in the newly created
Dublin Bay North constituency as an
independent candidate. She was again unsuccessful. She also contested the 2016 Seanad election for
Dublin University. In August 2016, the Asthma Society of Ireland announced that Power was taking up a €95,000 a year position as the charity's chief executive officer. In January 2018, she was appointed as the CEO of the Cancer Society of Ireland. In 2025 she will become CEO of the
Clúid housing body. ==Interests==
