McDaid told the "Irish Independent" on 1 June 2007 that he had received no help from Fianna Fáil headquarters during the general election campaign and that the party had treated him as a virtual independent. He warned that, consequently, the party should not take his support in the 30th Dáil for granted. This threat was followed through in November 2008 when he abstained from a vote on the Cervical cancer vaccination programme, resulting in his expulsion from the Fianna Fáil parliamentary party.
