Finally, summer is over! The relaxation, beach vacations and barbecues are finally behind us and in this post-Labor Day glow, Americans can focus on our prime national sport – the one with the late hits, flagrant fouls and crazy fanatics.Of course, I mean politics.And while this glorious season brings out the political junkies, it also brings out the political crazies. The extremists who have spent their time since the last election cycle tearing down the governments we elected and creating the conflict that makes politics a full-contact sport.As we speed into final lap of Midterms 2014, where do we stand?

He’s editor-in-chief of The Daily Beast, a CNN contributor, and the author of multiple books including the recently released: “Wing Nuts: Extremism in the Age of Obama”…
