I gether that question 2 would allow Massachusetts to do like New York does, allow people to appear on the ballot as the candidate of more than one party.

In New York, what happens generally is that the Republicans have to suck up to the Conservative Party somewhat so the CP won't run a separate candidate and "split the vote." The Democrats have to do the same thing with the Liberal Party. I don't recall it helping things when I lived there so I'll probably vote against.
