Does Republican Chris Christie lack both self control with his temper and his weight?

Apparently he lacks the control that someone in higher office needs. Hiss response to a valid question about public schools was met with a "none of your business", yet being in the public it is our business. Isn't this lack of self control evident in his enormous weight as well. Joe Scarbourough asked the same question and got anm answer, so is it only his constituents that he can't control himself with? He used his son as an excuse to use a public plane to go to his child's baseball game and to fly to a Republican Fund Raiser, is that too none of our business?
