Rep. Birmingham was named alternate delegate to the Democratic slate for the 1932 Democratic National Convention (DNC) by State Committee Chairman Frank J. Donahue (Boston Globe, March 11, 1932, p. 1, 22).
The slate was composed of supporters of Al Smith. Delegates-at-large included U.S. Senator David Walsh, Massachusetts Gov. Joseph Ely, and Ex-Mayor John Fitzgerald.
The delegates had given a pledge to vote for Smith, if they are elected.
Fitzgerald withdrew as a delegate-at-large, and Sen. John Buckley and Rep. Birmingham were considered to replace Fitzgerald.
Mayor Curley, a supporter of Franklin Roosevelt, said he would put together a pro-Roosevelt slate of delegates for voters.
Voters were scheduled to go to the polls to April 12 to vote in the presidential primary, where they would have a chance to vote on the slate of delegates to the DNC.
