{"kind":"user","text":"We standardize vote shares across elections by computing their z-scores so that we can measure Obama\u2019s electoral performance in each state relative to his average performance of that year. That is, we subtract the mean from Obama\u2019s vote share in each election and then divide it by the standard deviation. We regress Obama\u2019s 2012 standardized vote share on his 2008 standardized vote share. What is the estimated slope of the regression model? Please round to the nearest thousandth."}
