Progressives reconvened in Chicago and endorsed the formation of a national Progressive Party.
The party was funded by publisher Frank Munsey and businessman George Walbridge Perkins, who served as executive secretary.
At their convention on August 5, the new party chose Roosevelt as its presidential nominee and Governor Hiram Johnson from California as his vice presidential running mate.

The Progressives promised to increase federal regulation and protect the welfare of ordinary people.
At the convention, Perkins blocked an antitrust plank, shocking reformers who thought of Roosevelt as a true trust-buster.
The delegates to the convention sang the hymn "Onward, Christian Soldiers" as their anthem.
In his acceptance speech, Roosevelt compared the coming presidential campaign to the Battle of Armageddon and stated that the Progressives were going to "battle for the Lord."

Most of progressive politicians remained in the Republican Party.
