Executive overreach has been the growing problem since at least the 80s. The actual term "unitary executive" dates from then. The problem is the government has gotten too big. Congress can't or won't rein it in. The President doesn't have the scope to do it either. So in effect, alot of power is giving to the various organizations, and under unitary executive power, the President devolves his authority to the various organizations. This leads to the growth of unaccountable bureaucracy. I know this sounds contradictory but it isn't. The bureaucracy reports to the President who under unitary executive theory is their only real boss. An absent boss if the best kind of boss. The twinned parties like this because they can force through policies they really, really want when they hold the executive, but everything else sorts of just happens.
