The following year, Weaver accepted the decision to form a new party (called the People's Party or Populist Party) and published a book, "A Call to Action", detailing the party's principles and castigating the "few haughty millionaires who are gathering up the riches of the new world". He attended their convention in Omaha, Nebraska, in July 1892. After Polk's sudden death in June, Weaver was considered the front-runner for the nomination. He was nominated on the first ballot, easily besting his closest rival, Senator James H. Kyle of South Dakota. Weaver accepted the nomination and promised to "visit every state in the Union and carry the banner of the people into the enemy's camp". The vice presidential nomination went to James G. Field, a Confederate veteran and former Attorney General of Virginia.
