Most successful legislators have turned out to be awful Executives because they confuse "getting something done" for "doing the right thing". They confuse consensus for leadership
Hence the need to use a bit of common sense when choosing who to support for your next president. That person is going to be the CiC of our military, and the spear point of our foreign policy for years to come. They'll also set the tone for the entire administrative machinery of our government, including all of the alphabet agencies.
I'm afraid that I'd rather entrust those vital responsibilities to someone who has a demonstrated track record of successfully running a large organization, be it private or public.
Choosing a former legislator to be the next president is akin to electing a senior board member of a corporation to be the next CEO, simply because he sounds good, and has served near the top. That's just nuts.
Legislators do learn that you can’t fire the voters and volunteers. That you have to make yourself clear to both if you want to get anything done.
If we’ve learned anything this year, involved voters don’t just “move on” from issues that they deem vital.
