#' Fording's State Ideology Data (adapted, with E.R.A. status)
#'
#' This data set comes from Richard C. Fording (\url{https://rcfording.com/state-ideology-data/}) and used in Berry et al. (1998). The data set includes state ideology data (measured at the state/legislature and citizen levels), for each year between 1960 and 2018. These data will be updated as Fording updates the data. This data set enables inclusion of a variable measuring state-level policy adoption by year. As an example, the data set also include a variable measuring the ratification of the Equal Rights Amendment as depicted in Soule and King (2006).
