What is the most powerful branch of goverment?

You can make an argument for any of them, but I'm going to
go with the Presidency or executive branch.  Here's
why:

Congress has a lot of power.  In fact, it has all the
power to make laws.  So you would think they have the most
power.

But in our current system, with the power of the
media and all, the President has the most power.  He is the one person that just about
everyone in the country recognizes.  When he talks, the TV stations cover his speeches
and pay attention to what he says.

This means that the
President, more than anyone else, can decide what issues are going to be on the agenda. 
In addition, he has more of an ability than anyone else to get people to pay attention
and listen to his point of view.
