Bernard "Bernie" Sanders (born September 8, 1941) is the junior United States Senator from Vermont. He previously represented Vermont's at-large district in the United States House of Representatives. Sanders also served as mayor of Burlington, Vermont.
Sanders is a self-described democratic socialist, and has praised European social democracy (though he has also criticized its contemporary "Third Way" departure). He is the first person elected to the U.S. Senate to identify as a socialist. Sanders caucuses with the Democratic Party and is counted as a Democrat for the purposes of committee assignments, but because he does not belong to a formal political party, he appears as an independent on the ballot. He was also the only independent member of the House during much of his service there.
