 please include a sentence or two as to
how the separation of powers influences American politics.  Two points
that we discussed in class were 1)The separation of powers creates antagonisms
between the executive and the legislative, and both branches of government run
against each other during campaign season, often blaming one another for the
problems affecting the country; 2)Although the President is the head of his
political party, the separation of powers makes it difficult for him/her to
control the behavior of his/her party’s members in Congress.  This is due
to the different constitutional duties of the President and the Congress, and,
as such, their priorities will differ despite the fact that they are of the
same political party
