One is a woman, who is DA. She makes Martha Coakley seem like Bill Clinton when it comes to charisma, and will probably finish 4th, despite the fact that she appears to be the choice of the GOP establishment. She's from Brockton, MA, and has a voice like Mahvin Haglah.
The other one is a complete queen who started some govt watchdog group and has ridden pension reform to the top of the polls. Smart enough guy, but just a nasty little shit of a human. He will probably win, but it's more than a little funny to see all these conservatards rally around him while ignoring the fact that he is completely fucking flaming. Not in a Santorum "Is he...?" kinda way, either. More like a second he opens his mouth way.
Independent is a war hero Marine whose dad was a GOP rep out in the backcountry here. He came from Iraq and jumped on the Tea Party train, and then suddenly decided that he was an Independent moderate a few weeks ago based on the advice of his GOP strategist wife. Absolutely no one is buying it. Total wild card, though... and while I would never vote for the guy, he is just the most Mayor-like of the bunch.
The Dem is a total dinosaur from the 60s, who has been in Congress, but jumped ship when redistricting put him in the crosshairs. He was actually a Freedom Rider during the Civil Rights movement, and seems like a nice enough guy who is running many years too late. Voting for him, but a chance he doesn't even make it to the General election after the primary runoff limits the field to 2.
