I'd rather not commit to centrism as a rule since policy needs to be dealt with on a case-by-case basis although I do prefer the possibility of balance the term implies. I wouldn't call it a partnership, either. More like ideally Democracy is its own benevolent despot with a "don't make me come over there" attitude. Not that there'd never be call to go "over there".
I think of the center as the balance also. My comments always take into account that we are forever changing, and what is the "Centre" today will not be the "Centre" in the future...
