You've probably noticed Peter Nicholas' article on the front page of the wall street journal on Monday. I don't think there is anything to be gained by declaring candidacy this early. It only gives the other side more time for attack ads. With recent crumbling of regulations, it is easier than ever for a few back room billionaires to carpet bomb elections all across the nation.
Meanwhile, please pay attention to your local and state governments and prepare for the mid-terms.
