Senate vs. House of Representatives

First, the Senate's main powers include the requirement to ratify all treaties with other countries, the power to try all impeachments, and the ability to advise the President on his government appointments.  Not included in these powers, however, is the power to initiate revenue-raising bills- this power is given to the House of Representatives.  On the whole, Congress itself has the power to raise revenue, "provide for the common defense and general welfare", regulate the "militia", and regulate interstate commerce...along with a few other responsibilities. In foreign policy, also, Congress has the power to declare war, combat piracy, regulate foreign commerce, and regulate military institutions. Congress holds a great deal of responsibility for the American people it represents.  Both the House and Senate are there to represent the will of the people, and they are also there to keep the other two branches of government in check.  Without Congress, the American people would not be properly represented.
