By constitutional design, only a third of the Senate is up for reelection at any given time. This is supposed to stiffen the body’s ability to rebuff populist passions that will inevitably arise from time to time and manifest in foolish and panicked legislation in the House of Representatives whose whole body is accountable to the voters every two years.
For the same reason, senators were not supposed to be elected directly by the people, but the corruption that seemed to attend every vacancy in the Senate caused progressives to push for reform. In 1913, the 17th Amendment was ratified. It was an advance in accountability but a blow to the Senate’s independence. After all, we already had one representative body, and its design was calibrated to reflect the actual distribution of population in the country. The Senate’s two-seats-per-state rule isn’t representative at all, so it’s hard to discern its purpose if all it does is act as a second directly elected legislature.
Republicans are on a roll to destroy America as we know it. They've shown their true colors and they ain't red, white and blue.
