Obama's 2008 Iowa Caucus victory speech video

After months of hilarious jockeying, the Iowa Caucus is finally here.  It's hard to imagine that just four years ago, Obama beat Edwards and Clinton there.  His victory speech is worth listening to, if not just for nostalgia's sake.  Though some progress has been made since Obama became president, some of his supporters have been left disappointed.  The biggest failure has been his inability (and the Republicans' unwillingness) to work together on anything substantive.
