The Fed will use politics to their own end. Dem/Repub doesn't matter. As long as there is a political reason, natural disaster reason, even man-made war/disaster reason for market drop all is well in joe six pack's mind regarding his 401k. What is NOT permissible, is an actual economic reason for a market drop. In these instances the market will be continually propped. "They" are more than willing to play off of political sides to allow market to slide.
