The US Congres is the most powerful legislative in the world. Its independence and its powers make it impossible for the presidency to be truly imperial. The Senate is especially influential since it allows its members to use a series of minority procedures, such as the filibuster, that exert a constant a priori pressure on the Executive. This institutional configuration is made extremely costly by the current partisan polarization. It is also, however, a functional equivalent to the theoretical parliamentary right of life and death on Executive powers.
