The one thing people need to consider is that Obama is going broke spending his campaign cash now. Romney cannot spend his cash until the convention. Then he will have 4 to 5 times the money on hand to spend. It is surprising it is even close considering the unbalance television assault in battle ground states. Also, the superpacs will be unleashed and will start spending too.
No incumbent wants to be under 50% near an election since undecided always break to the challenger. Obama will need an October surprise to survive. He does not value the law or America and will make any immoral sacrifice to keep his job. So, if you want to be scared, wait until October.
And as I figured, 0 had a good result on Thursday, skewing the poll for 3 days.
