\item \emph{Notes}: OLS regressions. The unit of observation is a county. 
Demographic controls: Urban (binary), District population (\%),  Log population, White (\%), Male above 21 (\%), Native (\%). 
Geographic controls: Railroad density (km per sq. km), Distance to state capital (log), Distance to state largest city (log), Latitude, Longitude. 
Economic controls: Farmers (\%), Manufacture workers (\%), Number of newspapers over eligible voters, Crop value change (log), (log) Distances to silver and gold mines. 
All regressions include state fixed-effects. 
Standard errors adjusted for spatial correlation in parentheses.
* significant at 10\%; ** at 5\%; *** at 1\%.
