Joseph Manchin III (born August 24, 1947) is the senior United States Senator from West Virginia. Manchin, a member of the Democratic Party, served as the 34th Governor of West Virginia from 2005 to 2010 and the Secretary of State of West Virginia from 2001 to 2005.Manchin has been known throughout his career to be a moderate Democrat, a fact which has allowed him to hold office in West Virginia even as the state shifted from one of the most heavily Democratic in the country to one of the most heavily Republican. He was elected governor by a large margin in 2004 and re-elected with an even larger margin 2008, even though in both years Republican presidential candidates captured the majority of West Virginia's votes. He won the special election in November 2010 to fill the seat of Senator Robert Byrd, the longest serving U.S. Senator in history, who died in office. Manchin was elected to a full term in office with 60 percent of the vote in November 2012. Manchin became the state's senior Senator when Jay Rockefeller retired in 2015. Wikipedia
