What does the senate have the power to approve?

Answer 1

The United States' law-making branch of government is divided into two chambers. The House of Representatives holds 435 members who vote on behalf of local districts apportioned by population size -- around 600,000 people reside in each district. The members are elected every two years, keeping them very accountable to the sentiments (and inexplicable whims) of their constituency. This means that the state of Wyoming sends one "at-large" member to represent its 500,000 people in the House, while California sends 53 members to represent about 34 million inhabitants. To counter the House's reactionary tendencies and the control it renders to big states, the Senate was created in the U.S. Constitution to be removed from the caprices of the populace and offer the smaller states a greater say. The Senate is comprised of 100 members -- two from each of the 50 states. This means that Wyoming -- a state with more cattle than voters -- receives as much of a say as California -- a state with an economy the size of France. Senators are subject to re-election every six years. The elections are staggered so that about one-third of the "upper" chamber faces a challenge in any given election cycle.
