In the 1980s and 1990s, many people moved in from out of state. Much of this immigration included the arrival of more liberal political influences of the urban areas of New York and the rest of New England in Vermont. The brand of Republicanism in Vermont has historically been a moderate one, and combined with the newcomers from out of state, this made Vermont friendlier to Democrats as the national GOP moved to the right. As evidence of this, in 1990 Bernie Sanders, a self-described democratic socialist, was elected to Vermont's lone seat in the House as an independent. Sanders became the state's junior Senator in 2007. However, for his entire career in the House and Senate, Sanders has caucused with the Democrats and is counted as a Democrat for the purposes of committee assignments and voting for party leadership.
