I don't see any inherent value in "centrist" views, or even necessarily civility. But I would like to see a leader who recognized the need for consensus. We need to stop using democracy as a mallet to beat the "other side" over the head with whenever "our side" gets a leg up. We need candidates who will say something like:
"If elected, I will represent all my constituents, not just those who voted for me. I pledge to refrain from signing any bill, or implementing policy, that doesn't enjoy broad support, or at least acceptance. You might not agree with all my ideas, or my party's ideas, and that's fine. It's my job to persuade you, to convince you that those ideas are worth a shot. If I can't do that, those ideas will have to wait."
