I know we are in a little (maybe big) bubble here in MA, but if our governor and legislature don't change the law of succession, we are going to have only one senator for 5 months, until a special election is held. Many are pushing for the governor to appoint an interim, so we can keep the needed vote in Congress, but the Democrats voted against this option five years ago, when Republicans wanted it. I think they are under pressure to get it done, but it shall be very interesting.
