The entire progressive-left argument and basic foundation principle is based on one thing, Saul Alinsky's key phrase, "The Ends Justify the Means." Basically, do what ever you have to, lie, cheat, steal, it doesn't matter, whatever you have to do to get where you want, to get what you want, do it.
For those unfamiliar with Alinsky, it's definitely worth your time reading up on this guy. He is for all intense purposes the entire foundation of beliefs that Cass Sunstein abides by and as most should know by now, Sunstein is Obama's wielder of power.
