Democratic primary.
Campaign.
The Democratic primary featured a rematch of the 1922 primary between Joseph Ely and John Fitzgerald.This time, Ely won with 54.7% of the vote.
Fitzgerald was forced to withdraw late in the race due to illness, though his name remained on the ballot, and James Michael Curley encouraged a vote for Fitzgerald against the "anti-Irish" Ely. Ely had previously lost the nomination for lieutenant governor in 1926 to another Irish candidate who withdrew from the race, Harry Dooley.
