“Every two years, the Commission publishes Federal Elections, a compilation of the official, certified federal election results obtained from each state’s election office and other official sources." The above link provides the primary, runoff and general election results for the U.S. Senate, the U.S. House of Representatives and, when applicable, U.S. President. The percentages given here are for the U.S. House of Representatives midterm elections.

The value for U.S. House Election Vote Percentage (Dem) is obtained by dividing the number of votes cast for the Democratic party by the total number of votes cast in the election in each state. Similarly, the percentages for the other parties' shares of the vote is obtained by dividing the number of votes cast for the given party by the total number of votes cast in the election in the state.

We do not provide the vote percentages for the other parties because they are generally very small, except in Vermont, where, for example, Bernie Sanders received a plurality of independent votes in 2000, 2002 and 2004, resulting in very low Democratic vote percentages.
