When you refer to Republicans as "Pugs" I think that shows the tone and attitude. I wouldn't cooperate with that either.
In fact, there are a whole lot fewer "lefties" than centrist/moderates in the democratic party right now, and they will play ball. Hopefully, it won't end up with Romney screwing them the way Bush did, but it likely will.
It's "nice" to talk in terms of tone. Maybe we can have a new cabinet level position....Secretary of Tone.
