Gregory was reported to have asked
Socialist Party TD
Joe Higgins to run in the by-election to succeed him, but Higgins declined as he had already agreed to stand for the Socialist Party in the
concurrent European elections.
Fine Gael Fine Gael's candidate at this election was Senator
Paschal Donohoe.
Fianna Fáil Dublin Central was the home constituency of former
Taoiseach,
Bertie Ahern, who had resigned in 2008. Ahern's brother, Dublin City councillor
Maurice and fellow city councillors Tom Stafford and
Mary Fitzpatrick sought the
Fianna Fáil nomination for this by-election. Stafford withdrew his candidacy on the night of the selection convention, and after a 64–17 vote Maurice Ahern was selected as the Fianna Fáil candidate.
Gregory group While not a party officially, Tony Gregory's political machine had long elected candidates in Dublin city. Dublin City Councillor
Maureen O'Sullivan, formerly Gregory's election agent, was backed by Gregory's allies to run in this election.
Labour Party Senator
Ivana Bacik, the sole candidate to seek the nomination, was chosen as the Labour Party candidate for this election on 5 May. Incumbent TD for the constituency
Joe Costello was her director of elections for this election. Bacik had been accused of being "parachuted" into the constituency as she did not live there.
Sinn Féin There had been some early speculation that newly elected
Sinn Féin leader and incumbent
MEP for Dublin
Mary Lou McDonald would contest this by-election, but the entry of Dublin City Councillor
Christy Burke into the race effectively ended her chance of running. On 11 May, Burke was confirmed as the Sinn Féin candidate at this election.
Other parties The
Green Party nominated solicitor David Geary, also running in the concurrent
city council election, as their candidate at this election. Other candidates included
Malachy Steenson of the
Workers' Party, Paul O'Loughlin of the
Christian Solidarity Party and Patrick Talbot of
Immigration Control Platform. == Campaign ==
