I was curious to find out the balance of state legislatures across the country, with redistricting in 2010 in the back of my mind. I was(n’t?!) surprised to find that the wiki articles for state legislatures varied widely in content, quality, and completeness. The Massachusetts state legislature article is pretty good, and is broken down into Massachusetts House of Representatives and Massachusetts Senate. These articles may or may not be up to date.
What definitely needs work: Massachusetts House Elections 2006 and Massachusetts Senate Elections 2006. Please head over to these two links and contribute what you know, citing sources if possible. Prompt other folks to update the MA Lege wikis, as well as the wikis for the legislatures of other states. Good data is a nice part of democracy.
