I started with the official candidate list as published by the Secretary’s office. The Green and Libertarian parties each list one candidate on their sites. The Republicans have a few more candidates that are not on the Secretary’s site; some of them I could verify as write-in candidates, so I assume the rest are as well. The Democrats’ candidate list looks like a straight reprint (although it’s missing the candidates for the Senate seat in Berkshire et al.)
Non-party candidates are at the mercy of mentions in the media or online, as the Secretary’s office hasn’t published that list yet.
I then cross-checked the list against the Office of Campaign Finance list of campaign committees. There are three new committees that are not on my list because I can’t find any evidence of an actual campaign (Looby, Devers, and Plasse).
Most of the web sites came via Google, although there are a few sites out there with local candidate links, or partisan links such as GOP News.
This is a work in progress, as I assume that there are more candidates with web pages out there, or will be added as we approach the general election.
I’m maintaining the list in a spreadsheet, which will assist in revisions and the full-scale reorg after the primary.
Feel free to link to this or use it, but I’d prefer some sort of credit.
Suggestions for improvement are also welcome.
