Pennsylvania firing someone is not the same as Massachusetts firing someone. Massachusetts is a socialist/liberal social engineer state. So Romney not be able to win re-election is kind of a plus for him, it shows he governed as a conservative.
Mass arguably is to the economic right of Penna at the state level (though certainly not at the federal or municipal level).
Yeah, I've frequently noticed that a lot of our state legislators including much of the leadership come across more like particularly wishy-washy moderate Republicans than anything else.
