Soccer moms, or their grandmothers, have always been the root of all evil. At least that’s what John Lott seems to be saying in his paper How Dramatically Did Women’s Suffrage Change the Size and Scope of Government? Give women the vote, it appears, and very soon you’ll have the nanny state. The paper itself, available for download in *.pdf format, is long and academic, with lots of stuff about differential economic incentives, statistical regression and so on. It does, however, include an impressive graph that summarizes Lott’s basic point.
