Imagine McCain who already have had several heart attacks being elected. I do not trust in his health to live through 4 years if making it into office.
That would mean Palin becoming governing president.
A total nightmare of a maximum worst case scenario.
Anyhow I think Obama will win in the range of 55:45 to maybe even 60:40.
I also hope we get spared the carricature of election-aftermath we have seen the past two times when elections were tried to be rewritten at the green table (with success). A result not as tight as 51:49 again would helpt against this - and escaping the 51%-side then boasting with claims it had a "substantial majority" also would be appreciated.
German news yesterday reported that McCain also asked for financial campaign support at the Russian UN representation (you know: these types with the letters JFK in their eyes - or was it KGB?)
