He was elected to Dáil Éireann as a Fine Gael Teachta Dála (TD) at the 1969 general election for the Monaghan constituency. He was re-elected at each subsequent general election (for Cavan–Monaghan from 1977) until he lost his seat at the 1987 general election. Conlan's son Seán Conlan served as a TD from 2011 to 2016.
