This story is excellent and shows how weak Obama is. He has lost a lead he had in two states. They call Colorado and Minnesota swing states but they mostly go Republican. Obama was ahead of McCain in both of those states but now McCain is ahead in Colorado.
Obama needs to worry about traditional blue states. McCain feels comfortable with New Jersey because he has a shot there. Obama also needs to worry about the Battleground states. McCain is more likely to take all four of them this year.
