Pro-abolition Arguments in favour of the bill included: that abolition would save money; that the number of legislators is too large relative to the state's population; that the method of selection is elitist and undemocratic; and that the Seanad is a powerless rubber-stamp. In an opinion poll for
The Irish Times the week before the referendum, the reasons given by prospective yes-voters were: cost (43%), lack of power (16%), superfluity (14%), to reduce the number of politicians (8%) and lack of democratic election (5%).
Labour, Although Sinn Féin opposed the bill in the Oireachtas and argued that the Seanad's future should be discussed by the
Constitutional Convention, A non-party pro-abolition group called "One House" launched its campaign on 2 September 2013. Opponents alleged that the participation of its head, Kieran Mulvey, compromised his professional position as chairman of the
Labour Relations Commission.
Desmond O'Malley, founder of the
Progressive Democrats, called for Seanad abolition and additional political reform. The Fine Gael campaign claimed that the annual net saving to taxpayers of abolishing the Seanad would be €20m, a figure disputed by opponents. The Referendum Commission wrote to the Oireachtas finance officer, who put the annual cost of the Seanad at €8.8m in pay and expenses for Senators and their personal staff; €9.3m in support and infrastructure; and €2m in pensions. The officer said that it was not possible to estimate how much of this cost would be saved by abolishing the Seanad.). The
Green Party opposed abolition as concentrating power in a "smaller political circle". On 25 September 2013 the
Reform Alliance, of Oireachtas members expelled from Fine Gael for opposing the
Protection of Life During Pregnancy Act 2013, called for a No-vote. The
Workers' Party characterised the bill as "a power grab by the
kitchen cabinet within the cabinet".
Independent members of the Seanad were opposed to its abolition. In 2012,
Michael McDowell,
Joe O'Toole,
Noel Whelan,
Feargal Quinn and
Katherine Zappone published a 30-page blueprint for reform of the Seanad, with the slogan "Open it, don't close it", which was discussed in the Seanad. They formed the "Seanad Reform Group", which in May 2013 became "
Democracy Matters", to lobby against abolition. In 2013, two groups of Senators and one group of TDs each introduced a separate bill proposing to reform the Seanad by replacing the restricted-franchise
Vocational panel elections with general-franchise elections. Several former
Taoiseach-nominated senators from
Northern Ireland endorsed the opportunity the Seanad provided for cross-border input to the state's politics. Several TDs from the governing Labour Party, including its chief
whip Emmet Stagg, said that they would vote against abolition in the referendum, while supporting the bill in the Oireachtas. The
Union of Students in Ireland campaigned for a no vote. Commentators including
Vincent Browne suggested that Enda Kenny's 2009 announcement of his intention to abolish the Seanad was a
U-turn from his position of several months earlier, and an impulsive publicity stunt announced without consulting any party colleagues.
Breda O'Brien suggested voters should tick the "No" box on the ballot and also write the word "Reform" on it; a suggestion endorsed by
Fintan O'Toole despite the risk of thereby
spoiling the ballot. Both columnists characterised the government's putative reform of Dáil procedures as a charade to disguise a migration of power from the legislature to the cabinet and the
Economic Management Council. ==Course of the referendum campaign==
