Why would it head up? You think the market is relieved that the US is going to lose Greenie?
Uncertainty - both in the fact that no one still knows who, and once they know who they won't know what the "who" will do - is bad for markets. Unless the new guy is announced and then goes right away to center stage advocating sharp increases in rates, I think you're going to see a move down, not up, in the USD. There are my thoughts and reasoning.
Care to explain why you think otherwise?
