In 2004, Bacik’s book Kicking and Screaming: Dragging Ireland into the 21st Century, is published by The O’Brien Press.
In 2007, she contested the Seanad Éireann elections for the third time in the Dublin University constituency, and is elected to the third seat, behind sitting Independent senators Shane Ross and David Norris. She initially sits as an Independent senator.
In February 2009, Bacik is included in an ‘All Star Women’s Cabinet’ in the Irish Independent. In March 2009, she confirmed claims made on a TV programme that she had taken two voluntary pay cuts of 10% in addition to a pension levy. In June 2009, she is the Labour Party candidate for the Dublin Central by-election. She comes in third with 17% of the first preference votes. She joins the Labour Party group in the Seanad in September 2009, and becomes Labour Party Seanad spokesperson for both Justice and Arts, Sports and Tourism. In November 2009, a feature by Mary Kenny of the Irish Independent includes Bacik in a list of women who “well deserved their iconic status.”
In May 2010, Bacik seeks Labour’s nomination to contest the next election in the Dublin South-East constituency but is not selected. In December 2010, she is added to the ticket as the second candidate beside Labour Party leader, Eamon Gilmore, in the Dún Laoghaire constituency for the 2011 Irish general election. Gilmore tops the poll, with Bacik receiving 10.1% of first preference votes but she is not elected. She is re-elected to Seanad Éireann at the subsequent election, after which she becomes Deputy Leader of the Seanad. She holds her seat in the Seanad in 2016 and in 2020.
On April 27, 2021, after the resignation of Eoghan Murphy from his Dáil seat in Dublin Bay South, Bacik announces her intention to stand in the upcoming by-election. She campaigns with an emphasis on providing affordable housing, as well as improving healthcare and childcare, tackling climate change, and achieving “a true republic in which church and state are separated.” During the campaign, she describes herself as having “more bills passed into law than any other Senator, on issues such as workers’ conditions, women’s health rights, and LGBT equality”. She also campaigns on increasing the number of sports amenities for children in the area, calling for unused Defence Forces football fields at the Cathal Brugha Barracks to be freed up for local sports, with the suggestion rejected by Fine GaelMinister for DefenceSimon Coveney. Fine Gael complains to RTÉ after she features prominently on National Treasures, a prime-time TV show broadcast by RTÉ during the campaign. RTÉ has strict rules about fair coverage of candidates during campaigns. The national broadcaster blames an “inadvertent error” for the programme being shown three days before the election. A steering group within the broadcaster tells Fine Gael that “the broadcast should not have happened.” Consequentially, RTÉ has to show a special report on the by-election on Prime Time to “ensure fair coverage is given to all candidates.”
Bacik wins this election, receiving 8,131 (30.2%) first-preference votes. It is her fourth attempt as a Labour candidate, and she expresses her delight at the success at the count centre in the RDS. Following the election, she is described by The Irish Times as “a formidable activist and public intellectual” and that Fine Gael’s perceived antipathy towards their former TD, Kate O’Connell, may have contributed to the surge in support to Bacik from women voters. The newspaper claims that her election is “a long overdue morale boost” for Labour.
In March 2022, Bacik confirms she will run to succeed Alan Kelly as Labour Party leader. Kelly states that he believes that Bacik will succeed him. On March 24, 2022, she is confirmed as Labour Party leader unopposed at a party conference in Dublin. In a speech, she says she will focus on the rising cost of living and the serious and global problems facing the country. She pledges that Labour will fight the next election as a “standalone party” rather than joining any left-wing alliance.
