Mark C. Miller, the Green Party nominee in 2010 in the Massachusetts State House race (Berkshire 3rd district) who received 45.02% of the total vote, will run for that same seat in a special election later this year. See this story. In 2010, Miller was in a two-person race with a Democrat. That Democrat has now been nominated for a high position in state government, so it is overwhelmingly likely that the seat will soon be empty and a special election will be held.

UPDATE: see this article about Miller’s upcoming run, which ran in the Berkshire Eagle on June 12.
