Progressive Party (United States, 1912)
The Progressive Party was a third party in the United States formed in 1912 by former President Theodore Roosevelt after he lost the presidential nomination of the Republican Party to his former protégé, incumbent President William Howard Taft. The new party was known for taking advanced positions on progressive reforms and attracting some leading reformers. After the party's defeat in the 1912 presidential election, it went into rapid decline, disappearing by 1918. The Progressive Party was popularly nicknamed the "Bull Moose Party" since Roosevelt often said that he felt "strong as a bull moose" both before and after an assassination attempt on the campaign trail.
John Bull (gunman)
Bull was next heard of in 1866, when he arrived in Virginia City, Nevada. By this time he was partnered in a gambling operation with fellow Englishman Langford M. Peel, known as "Farmer" Peel, a former soldier. During this time, famed writer Mark Twain became friends with Bull, writing later of how well they had gotten along, and particularly of a joke that Bull had once pulled on Twain during the winter of 1866.
