The 3rd US presidential debate takes place
tonight. It is intended to focus on
foreign policy, therefore it is the only presidential debate of actual significance.
This is not because economic policy is unimportant, but because the US president
does not and cannot determine US economic policy. That is done by the US
Congress over which the president has no control.
Article 2 of the US Constitution vests the president with
executive powers (the power to take certain actions), but not legislative
powers (the power to make laws). The president’s executive powers include the
power to enter into foreign treaties, to appoint foreign ambassadors and to act as
Commander-in-Chief of the US armed forces.
The fiery debates about economic policy cast a lot of heat,
but no light, on what sort of presidency each candidate can actually offer.
Tonight’s debate is therefore the most meaningful indicator the world will get
as to whom should command the world’s biggest military for the next four years.
