Divided Government in the American States: A Byproduct of Legislative Professionalism?

Abstract

Since World War II, divided government has become increasingly common in the American states. A significant component of the increase is the deterioration of Republican fortunes in state legislatures: after the 1990 and 1992 elections, for example, only five state legislatures were controlled by the Republicans. I shall examine the hypothesis that the professionalization of state legislatures makes legislative service more attractive to Democratic candidates and less attractive to Republican candidates, because full-time legislative service is incompatible with another career, and Democrats, on average, have less lucrative career opportunities than Republicans. Statistical analysis of post-World War II legislative elections outside the South is consistent with the argument: other things being equal, every ten-thousand-dollar increase in real biennial legislative compensation is associated with approximately a 1% increase in Democratic legislators.
