Hell, give me the money to push my campaign with and I’ll run even without a guarantee of winning. (But it’s got to be enough money that the average voter knew that I was there and participating).
And yes, if elected I would serve. I would put all the available energies at my disposal into doing the best job possible and to hell with the rest of my life afterwards. I’d pay staffers to drill me on details to keep me alert and cognizant of the grainy particulars of what I’m dealing with. And I’d have political pundit-philosophers from several wings of various parties to throw my vision and viewpoint stuff at and have them attack what they dislike about it, or about what they hear it to be. And I would try to speak to the American people on a similar basis, to explain how I perceived things and lay out what I was trying to do, and why. And wherever could incorporate or compromise to include opposing/alternative viewpoints, without losing my momentum within my own agenda, I’d do so. But I’d still mostly want my own stuff getting done.
And if it looked like I was worth a damn at it, I’d run for re-election
