As Jon Chait pointed out, a statistical model based only on economic/structural facts suggested that Democrats should lose only about 45 seats. This is only one model and it suggested the worst-case scenario for Democrats; other “structural” models put the number in the 20s and 30s. In other words, the Democrats’ losses were about 20 to 40 seats in excess of what we would expect from the effects of the economy and back-to-back wave elections. Remember, Reagan’s Republicans encountered similar economic headwinds in 1982, and they lost 26 seats, a baker’s dozen of which can be directly chalked up to the intervening redistricting.
The one and only.
