Why in the United States is the direct leadership of the President so very important?no

This should bring out a variety of answers.  I would say
that there is a both a practical and symbolic rationale behind why the leadership of the
President is so very important.  Practically speaking, the President is a symbol for
their political party.  This carries with it a great deal of weight and recognition for
this party is going to be subject to name recognition with the President.  If the
President is successful, the party will stand to benefit from that success, as well.
 Conversely, if the President is unsuccessful, the party suffers.  This can end up
translating to altering the balance in the two party system of the Legislative Branch in
terms of number of seats for each party in midterm elections.  The President's rapport
with Congressional leaders can also be vital for the passage and introduction of
legislation, which again is reflective of the President's standing.  If the direct
leadership of the President is received in a very positive way, the legislation they
propose and for which there is advocacy stands a greater chance of passage.  The
President's political capital becomes vitally important in a practical setting here.  If
the President enjoys little political capital, their direct leadership is hampered
significantly.  From a symbolic standpoint, the President of the United States is tabbed
with the cliche, "leader of the free world."  In this instance, there is some truth to
the cliche.  The President is an international symbol.  Whatever else may come of the
nation and its prestige amongst the world countries, there is a certain political value
when a nation "hosts" the President of the United States or when there is a sit down
between a leader of a country and the President of the United States.  This perception
is also felt on a domestic level.  The perception of the President on the part of their
fellow American citizens can be as important, sometimes more important, than what is
actually done.  If the President is perceived to be weak and ineffective, then there is
a good chance that their direct leadership will suffer.  The President's perception
plays a critical role in their ability to govern.  This is a part of the component of
direct leadership, and an essential leader why it is so important in the United
States.
