Nate Silver's FiveThirtyEight has forecast some great results in past elections predicting Obama would beat John McCain in march of 2008. His prognosis has been correct significantly more than wrong, making him someone you want to follow into next week. He recently talked of the possibility of November 4, ending in a senate tie between Democrats and Republicans. And if that happens, who comes to the forefront to break that tie? Vice President Joe Biden. Joe may be outspoken and have gotten off some zingers, but he's solidly Democrat and staunchly backs the President. The Dems don't want to and may not have to settle for a split but should it happen, this is their cushion.
