He served as a Teachta Dála (TD) for the Mayo South constituency from 1943 to 1965.
He attended the local national school and later worked on his father's large farm, going on to inherit it, as his other brothers were all in Holy orders.
[2] In January 1956, aged 53, Blowick married nineteen-year-old Teresa O'Malley of Castleburke, County Mayo.
The party's representation dropped to seven seats after the 1948 general election but it was strong enough to be part of a coalition arrangement and Blowick was appointed to the Cabinet in the two Inter-Party governments (1948–1951, 1954–1957), serving under John A. Costello as Minister for Lands on both occasions.
[4] He died on 12 August 1970 in a Dublin hospital, leaving an estate valued at £9,771.
