No. The statement assumes "monsters" are the only viable leaders to solve tough issues. But that's a chick or the egg argument. People who run for office, are by their intrinsic natures monsters searching for power, money glory, fame, influence, etc. They are the types that will stop at nothing to get what they want, even if it means using people, lying, stepping over and on others, backstabbing, and other similar behaviors. It's a certain personality type that is drawn to politics, and thus it is the only frame of reference we have for an "effective" leader.
Even the Liberal leaders share these characteristics, and actively hide their nature to appeal to the demographic they want to get votes from.
