Usually when a politician speaks of change it just means that the politician has no experience. Now don't get me wrong I am willing to give Obama a chance, but it is to bad people did not see through this in the primaries. A great poltical television series to watch is "House of Cards" http://www.imdb.com/title/tt0098825/ this series will teach you alot about politics. I think Biden is a great choice, but the Republicans will use this to highlight Obama's lack of experience. And the Republicans will say "see Obama is not the change candidiate".
