New Orleans Political Machine

Sometimes I wonder whether New Orleans has some sort of political machine whereas no politicians are completely innocent from some type of corruption. Why I would call it a political machine because it seems that every politician is following the same path: Their behavior is always in question.

If a politician is black, however, he always try to play the race card whenever someone question his/her behavior. This is so disturbing because since the race card is always played, no one will ever listen if race is really the issue.
