I am sure the biggest contributor to Obama's victory was George W. Bush and his oil- and war industry linked neocon mentors.
Sorry, guys, I am impartial and can tell you that this last presidency has been the biggest disaster in US (make it World) history. Eight year of lies and fraud right from the first day.
Don't blame Obama for that even before he starts. Better respect your next president, He deserves your support, because no president ever had to start under such dire circumstances. On top of that he is showing that partisanship is not the way to go.
