During his time as an elected official, O'Neill was criticised for "doing little to solve Dublin's dreadful housing problem".[2] The problem could not be solved without generous government aid, which was not forthcoming, as the UK was involved in a world war.[2] In an effort to retore peace during the 1922 Battle of Dublin, O'Neill chaired a committee of prominent women who met with military leaders on both sides.[4] O'Neill was elected to Dáil Éireann as an independentTeachta Dála (TD) for Dublin Mid at the 1922 general election.[5] He did not contest the 1923 general election and he was an unsuccessful candidate at the September 1927 general election.
He was elected to the Irish Free StateSeanad Éireann at a by-election on 20 June 1929 to fill the vacancy caused by the resignation of Henry Petty-Fitzmaurice.[6] He was re-elected to the Seanad for a 9-year term in 1931 and served until the Free State Seanad was abolished in 1936. He was nominated by the Taoiseach on 2 January 1940 to the 3rd Seanad. He did not contest the 1943 Seanad election.
