Along the Mississippi Gulf Coast during the last presidential election, there were signs every where, mostly for Bush. This presidential election there are very few signs. And surprisingly, Obama signs are outnumbering McCain signs 6 to 1. Latest polls show McCain ahead by just 10%, +- 4.6%.
Based on my very unscientific sign ratio, the reverse is true. Given the polls have a 4.5% plus/minus error, maybe the race is actually closer in Mississippi for Obama than the polls would indicate. We'll know soon enough in a couple of weeks.
