Don’t forget that pesky old 17th Amendment passed during the Wilson presidency. Prior to the 17th Amendment U.S. Senators were chosen by the State Legislatures from each state. After the passage of the 17th, the U.S. Senators were chosen by a popular vote of the people of each state.
This removed a very strong check on Federal Power that was held by the states. Prior to the 17th you had the voice of the people in the House of Representatives and the voice of the State governments in the Senate. After the passage of the 17th, the governments of each of the states had no voice at the Federal level.
