[1][2][3][4] Hoopes ran to be the Judge of the Court of Common Pleas in Berks County, Pennsylvania, with the Socialist nomination in 1927, 1929, and 1957.

[12] Hoopes was selected to serve as the chairman of the Socialist Party of America's 1934 national convention by a vote of 69 to 61 against George E.

On February 7, 1937, the Socialist Party of Pennsylvania called an "Eastern States Conference of Social Democratic Organizations" in Philadelphia which moved forward towards establishing a new organization, the Social Democratic Federation.

[16] Hoopes was named to the 7 member committee which issued a call for a National Convention in Pittsburgh, to be held May 29–31, 1937.

[1][17] During the 1930 campaign Hoopes had been arrested for attempting to conduct a political meeting without a permit, but the charges against him were later dropped.

[23] On June 4, 1944, Hoopes was selected unanimously as the vice-presidential running mate to Norman Thomas, who was seeking the presidency for the fifth time.

[24] The Thomas and Hoopes presidential ticket placed fourth in the general election and received 79,019 votes.

However, the sixty delegates to the Socialist Party of America's national convention chose not to spend large amounts of money or effort on campaigning for president and would instead seek write-in votes for Hoopes and Friedman.

[1] On September 25, 1989, Hoopes died in a nursing home in Sinking Spring, Pennsylvania of natural causes.
