What's next for America? Washington DC

This trip will cover, by plane, train and a probably far too big automobile, 8,000 miles, 10 states, and perhaps a trip over the border to Mexico.
Along the way I am going to be asking a different person each day, 'what is next for America'. A deliberately vague question, the hope is that we hear some interesting voices, be they on the economy, the political system and who will win in 2012, or on America's place in the world.
At the end of week one I have seen Obama being (apparently) helicoptered into the White House, met the protester who has been camped outside since 1981, spoken to Washington's finest about immigration law, and eaten fried pickles. A good week. Not all of them are in the videos, but a few.
I will be in Washington DC for six days until the trip takes me to South Carolina, Georgia, Alabama and then down to some of the border states.
