Why does each state in the US have 2 US senators?
The Constitution of the United States provides for a bicameral legislative body to ensure an equality of representation among the states. If there was just a single legislative body, in the interest of freedom and sovereignty of the states that legislative body would be elected according to population and a state with more people than another will elect more representative to the Congress. This gave the smaller states a reasonable concern and during the Constitutional Convention where the Constitution was written, there were many suggestions as to how to appease the smaller states but it was ultimately the “great compromise” also known as the Connecticut compromise where an agreement was reached and the bicameral legislative bodies of both the House of Representatives and Senators became what is now called Congress.
