Question: What political party was the candidate who garnered a million votes during the 1920 election despite being in prison, a member of?

Knowledge 1: 1920 United States presidential election
Socialist Party candidate Eugene V. Debs received 913,664 popular votes (3.4 percent), despite the fact that he was in prison at the time for advocating non-compliance with the draft during World War I. This was the largest number of popular votes ever received by a Socialist Party candidate in the United States, although not the largest percentage of the popular vote.

Schwarzenegger ran for re-election against Democrat Phil Angelides, the California State Treasurer, in the 2006 elections, held on November 7, 2006. Despite a poor year nationally for the Republican party, Schwarzenegger won re-election with 56.0% of the vote compared with 38.9% for Angelides, a margin of well over one million votes. In recent years, many commentators have seen Schwarzenegger as moving away from the right and towards the center of the political spectrum. After hearing a speech by Schwarzenegger at the 2006 Martin Luther King, Jr. breakfast, San Francisco mayor Gavin Newsom said that, "[H]e's becoming a Democrat [… H]e's running back, not even to the center. I would say center-left".
