I don't know about the election being uncertain, the surprise would probably be a large turnout, a greater than usual turnout would turn the current more or less even polls in the battle state to a democratic victory, maybe even control of the senate (I doubt they get the house, which is fine with me), thus the fear of uncertainty the market is reflecting here (together with the Spizer/Vioxx debacle in the financials and drugs in the dow) may be relieved.
