I agree with your Palin comments.
What do you mean about coming full circle? This will be London's third time hosting with no particular pattern that I see. They were the fourth (I think) host. What kind of circle do you mean?
I'm not sure what you mean by end of a rein (sic) for the Dems either, as they will almost certainly retain the Senate and I'd be somewhat surprised to see them lose the presidency. They could blow the House by then, I'll grant you that.
The idea that we should head to Brazil, Panama or the DR for stability is a bit odd to say the least.
Your last sentence is a major copout! If you're going to make a prediction, make one with some balls!
