I see the Senators and Representatives staying with in their parties not for any reason other than cronyism protections. I see them as no better than the mafia, and in many ways worse. The mafia is centralized in many ways geographically, while the D.C. mafia can reach the world with it's corruption, and make the American soldier do the dirty work, and us as tax payers finance it.
I think Congress as a whole, is shameless.
