This dude is my new hero. He is the poster boy for the Radical Middle. He has summed up most of my most recent concerns about America's future (namely extreme partisanship and special interest control.) I really have no idea what his political leanings are or how he has voted in the past, but I can tell you that he is the first politician in a while that I would describe as a leader.
He had his seat in the bag for the next six years. Easy money. But he said, "Eff this noise." And handed in his notice.
Furthermore, he has drawn attention to the fact that though politics has always been the bane of government, it has escalated to a point of irreparable damage. Basically the system is a broke and it would take an Act of Congress to fix it. Of course, therein lies the problem.
So I ain't telling anyone what to do, but I am taking into serious consideration his plea to vote out ALL incumbents. Maybe you should give it some thought, too. But only if you ever want to see any kind of effective legislation passed. If you are fine with every new bill having a hundred hidden riders and not making any substantial impact on it's original intention, then sure, keep voting how you always do.
