Vermont, New Hampshire, and Maine all used to be reliably Republican, but that very quickly changed in the 90s.
ME-02 is returning to swing district status.... and that's it! I'd say the women in the state got REALLY angry after the 2002 and 2004 Senate elections, when two Democratic women lost to two Republican men. Then it really started to change.
It doesn't seem likely or logical to me that female voters in these states felt personally offended by electoral losses by female Democratic senators and thus are angry at the GOP because of it. Women support Democrats by larger margins than men in every state in the country; your explanation doesn't make sense.
