The Progressives (Les Progressistes) is a social-democratic French political party associated to the centre-right Union for a Popular Movement.
In 1944 he was elected as a Democrat (Biemiller had abandoned both the Socialist Party and the Progressives by then) to the 79th Congress from the Milwaukee-based Wisconsin's 5th congressional districtRepublican incumbent Lewis D. Thill, with 88,606 votes to Thill's 78,834, Socialist former Assemblyman Edwin Knappe's 4,758, and 2,103 for Independent Progressive Irwin Aaron.
The Progressives won a majority government, and Ingaldson served as a backbench supporter of John Bracken's administration.
At a meeting of the British Drama League in the twenties, the Progressives' representative handed over to George Bernard Shaw royalties of seven shillings and fourpence, possibly on the takings of Pygmalion which had raked in the grand sum of £16.00.
