The Senate is the side of Congress where every state has the same number of votes (two). This is different from the House of Representatives, where states with more people have more votes than states with fewer people. This was decided at the Constitutional Convention, because small states like Delaware did not want the larger states to be able to decide everything. Also, only part of the Senate runs for election during elections. Every two years, 33 (two elections) or 34 (one election) senators are elected. For each state, this means that after two elections to the Senate, during one election no one will be elected to the Senate.
