Right Track - Republican or Democrat

For those non-Americans, who might be somewhat confused as to what exactly a Republican or a Democrat stands for, here is a great four minute video by a black state senator on why he switched parties.  I'm grateful to my friend Kevin for sending it to me.  http://www.youtube.com/embed/n_YQ8560E1w?autoplay=1

It has always been accepted that black people vote democrat, who profess to be the party of the little guy.  But is that really the case or just folklore?  Incidentally for further clarification, the reason that there is usually an elephant on this post is that it is the symbol of the Republican party.  The Democrat symbol is a donkey.  So you have a big lumbering animal or a fool - take your pick!
