It's clear that there's no guarantee of a Democratic victory in 2012 and especially if Barack Obama actually implements the policies that he campaigned on which must inevitably lead to the decline of the US economy.
On that point, it would be terrific if Obama won the 2012 election by an electoral college vote of 500-38.
Because it means that the US economy is back up and running and he has dealt effectively with the multitude of foreign policy challenges that the world faces.
Is that likely?
No, but it would be for the whole world if it happened.
