Max Baucus
Max Sieben Baucus (né Enke; born December 11, 1941) is a retired American politician and diplomat who served as a United States Senator from Montana from 1978 to 2014. A member of the Democratic Party, he was a U.S. Senator for nearly 36 years, making him the longest-serving Senator in Montana history. President Barack Obama appointed Baucus to replace Gary Locke as the 11th United States Ambassador to China, a position that he held from 2014 until 2017.
Scott Sales
In November 2016, Sales won an internal election among state Senate Republicans to be the president of the Montana Senate in the 2017 election. His opponent was Senator Eric Moore of Miles City. Although the vote was by secret ballot, it was described as a close case. He assumed office in January 2017. Sales broke with tradition in January 2017 by deciding to not sit with the state House in the customary beginning-of-session joint sitting to hear speeches from members of Montana's congressional delegation, the chief justice of the Montana Supreme Court, the Montana Superintendent of Public Instruction, and a Native American leader. Sales' choice to break from tradition was publicly criticized by former State Senate president Jon Tester.
