\begin{scriptsize}
\item \emph{Notes}:
2SLS estimates of the effect of 1908-1913 conscription into the Wehrmacht on support for radical right-wing candidates and on abstention. 
The unit of observation is a municipality. 
Standard errors clustered at the canton level in parentheses. 
Panel A: 2SLS estimates with radical right-wing vote as the outcome; 
Panel B: 2SLS estimates abstention as the outcome. 
Each column presents the estimation for a different election. 
All specifications include a quadratic polynomial in latitude and longitude ($ x+y+x^2+y^2+xy $). 
First-stage F-statistic is the Kleibergen-Paap rk Wald F-statistic of the first-stage estimation. 
* significant at 10\%; ** at 5\%; *** at 1\%.
