In Clare, de Valera had a new running mate, the GP Patrick Hillery. Hillery was a political neophyte: when De Valera told him to go to the Fianna Fail head office to sign the (party) pledge he thought he was being asked to give up drink. But he was assured that he would know all he needed to about politics after a campaign with de Valera.
