The whole, US splitting up in 2010 isn't overly farfetched. When you consider the state of the economy, which in a capitalistic society is the main objective of a country, is almost 11 trillion dollars in debt. The well to do states, or rather states that aren't suffering so bad will only want to support states with nothing for so long. There are also giant ideological differences across the united states (ex. Maine vs. Texas or even North Vs South). The United states, as Canada, simply take up too much landmass with people spread out too far to try and fit all people into their current systems.
Obama did promise change...
