Either Kennedy or Moulton would be the Democratic candidate if they jumped in. If they both ran, I feel like Kennedy would be a better idea for Democrats, as Moulton's district is much more competitive. If neither ran, it's Safe Republican, with Kim Driscoll having the potential to lose worse than Mark Roosevelt. On the third party side, Evan Falchuk is running again.
Neither Kennedy nor Moulton are going to give up safe House seats (Moulton's seat isn't really that competitive) for a governor's race that they probably wouldn't win. I mean, I'd happily vote for them, but they wouldn't want to take that risk.
They wouldn't have to give up their House seats.
Yes, but it would make everything much more difficult if they won both elections.
