This year, Massachusetts voters elect all 160 members of the State House of Representatives. There is a contest between a Republican and a Democrat in only 29 of those races. This is because of the massive weakness of the Republican Party, which has nominees in only 37 districts.
The only minor party nominee this year for Massachusetts state house is one nominee of the Veterans Party. The Green Party is ballot-qualified in Massachusetts, but Massachusetts makes it so difficult for a small ballot-qualified party to place nominees on its own primary ballot, the Green Party has no candidates this year for state house, or U.S. House, or U.S. Senate. There is one Green running for State Senate. The Working Families Party is also ballot-qualified, but it has no nominees for any office in Massachusetts this year, and will lose its qualified status. The Green Party will also lose its ballot status unless Cynthia McKinney polls 3%, which is unlikely.
