Format was a bit strained. Forcing 5 minutes of interaction between the candidates was a very contrived concept. McCain seemed angry and whinny and Obama ran out of steam in the closing moments.
A country of 200 million and we have 2 candidates. Strange and sad. Charles de Gaulle once said something like this about the political make up of France. And I para phrase "We have a country with over 200 varieties of cheese and one political party!" I think the US is in the same situation but then again that's just my 2 cents.
