If I wanted some one who could work with Democrats, I would vote for a Democrat. I want some one who will stand firm on conservative values, stand up to Democrats, and will aggressively turn our country back to our founding principles.
There is something to be said about certain times when you need the support of members of the opposing party to get things done, i.e., when we have a GOP President and Dem Congress, as Reagan did.
However, it’s very likely Romney, if POTUS, would have a GOP Congress to work with...”compromise” won’t be needed much.
There is a fine line between strong-arming the opposite party with charm and charisma to get things done ( like Reagan did) vs. just rolling over and playing dead.
