He was unsuccessful when he first stood as a candidate for Dáil Éireann at the June 1927 general election, in the Clare constituency, but was elected as a Teachta Dála (TD) there at the 1932 general election. He was re-elected there at every election until he lost his Dáil seat at the 1951 general election. In 1951, he was nominated by the Taoiseach to the 7th Seanad, and in 1957, he was nominated to the 9th Seanad.
