What political movement in the early 1900s finally loosened the southern pacific's grip over state politics?

Answer 1

The political movement that finally loosened the Southern Pacific Railroad's grip over state politics in the early 1900s was the Progressive Movement. This movement, characterized by its push for reforms such as government regulation of monopolies, campaign finance reform, and increased voter participation, gained momentum in California during this period. Key figures, including Governor Hiram Johnson, championed measures that aimed to diminish the influence of corporate interests like the Southern Pacific, ultimately leading to significant political changes and greater public control over state affairs.
