Three days after coming of age Bernard was returned as his father’s successor for Bandon Bridge, where the family had alternate control of the representation. (A public dinner in the town to mark his majority had been ‘suspended’ following the death of his grandfather, the 1st earl of Bandon, in November 1830.)
Bernard unsuccessfully contested county Cork as a Conservative at the general elections of 1832 and 1835. He came in again unopposed for Bandon Bridge on a vacancy in 1842 and sat undisturbed until his succession as 3rd earl in 1856. He died in 1877 and was succeeded in the earldom by his only son James Francis (1850-1924).
