President Barack Obama!

nothing much. he'll be as bad as the last one (well nearly) people will still be living in poverty, the U.S will still be fighting wars, the financial crisis will deepen, America will still choose to be ignorant of climate change.
i think your optimism is likely to wane.

i'ts not sour grapes on my part, i wish i had good reason for a different prediction.

What optimism? I'm ignorant to all of this 'change'.
How will this affect me/people I know? If he pulls the troops from the middle east I'd be happy. If he started thinking greener I'd be happy but meh he's just another politician. I don't quite understand the interest from people here in the UK.
