Obama is ahead by 10% or less in 5 states, which represent 51 electoral votes. If those states go for McCain instead, it's 278-260 for McCain.
Either NV or NH (but not both) could still go for Obama, and McCain would still have the winning margin.
Thank you for your posts.
You are better at explaining stuff than I am.
Just add Virginia and Ohio to McCain's side, and he's only 10 electoral votes short of victory.
