Charles Franklin: “In the House, the president’s party has lost seats in all but four midterms since 1862, and one of those, 1902, was a year the House expanded so the Republican gains fell short of Democratic gains that year. After 1934 it wasn’t until 1998 that the president’s party gained seats, then the rare event repeated in 2002. Not since.”“This regularity over 160 years is hard to attribute to the circumstances of the moment. Likewise the hope that ‘this year will be different’ has been a forlorn one. The size of the seat loss, on the other hand, has varied considerably and is correlated with presidential approval (Clinton in 1998 and Bush in 2002 were unusually popular, as was Roosevelt in 1934) and the state of the economy. Popular presidents lose fewer seats, unpopular ones more. Good times go with smaller losses, bad times with greater losses.”
