Sure they don`t matter DUmbass,that is why you are making a point of telling everyone they dont. 
SanFran Nan was saying the same thing. Getting two more yes votes in the house was more important than two governorships. I disagree with that view, considering that both of those newly elected dems are in purple districts, they might be wary of voting to liberal. Then again, two more votes shouldn't mean much when she has a big majority in the house already.
OTOH, governors are statewide offices, while I doubt there is much chance that New Jersey will swing red in upcoming congressional elections, Virginia might, and so might other states where moderate/independent swing back and forth.
