In less than a month, many Americans will participate in yet another critical election. I say “yet another” because we have recently experienced an unusual spate of critical midterm contests. For most of the post-World War II period, midterm elections were sleepier, less impactful events. The Democrats controlled the House of Representatives for 40 years up until 1994 and the U.S. Senate for 26 years until 1980. Since 1994, the House has flipped twice and the Senate four times. If the polls and projections are correct, the House will change hands once again.
