Gold might have a temporary swoon if Romney wins, but Uncle Ben isn't out until Jan 2014. Since he literally wrote the book on how the Depression-era Fed types didn't ease enough, you can bet he doesn't give a hoot what the politicians say. If he's quitting/going to be fired anyway, he's going to go out with a big easing bang. It's his legacy (he believes). Buy gold if it goes down.
It makes sense to keep eye on politics for investment purposes, but it is largely futile trying to link general political events to short-term specific market moves. In this respect the only clear point of U.S. election is that some uncertainty will be removed after tomorrow, clearing place for new uncertainties. In other words, market’s future is clear as mud; it would be good enough to get some clues about PAAS future, e.g. earning number reported on Wednesday and market reaction to it.
