The problem we have it that most of the media led by the BBC are all for Obama.
They were for Gore when Bush won . So you do not know the reality of the outcome.
People who support Obama like Labour supporters tend to be very vocal, and believe their own propaganda ( spin, lies).
They are from people who do not earn a living in the real sense of the word ie employed by the government.
I would not like to call it as people who vote Republican like people who vote Tory just do not make the same noise ( they don't have time as they are doing real work.)
The result will be close and may surprise the BBC.
