I can't help but remember back when the Bush-Gore race was in the hands of the courts and the economy, and nation itself, was in a malaise. All the pundits decreed that if Bush were declared the winner their would be a rally on Wallstreet because the Republicans were considered better for the economy.
Bush was confirmed. The stock market immediately fell.
To blame the recession, which is already here, on the likelihood of an Obama win is utter nonsense. The damage has already been done, both Obama and McCain insured that it will only be worse in the long run with the sell-out bailout, and both parties have played their part by catering to Wall Street instead of main street.
On the other hand, not an Obama win so much as a overwhelming Democratic win in congress could have an effect on Wall Street:

Again though, not enough to cause a recession - that appears to already be here to me.
