\item \emph{Notes}:
2SLS estimates of the effect of conscription into the Wehrmacht on support for radical candidates and abstention across space and time (Equation [\ref{2SLS_MODEL}]). 
The unit of observation is a municipality $ \times $ election $ \times $ candidate. 
Standard errors clustered at the municipality $ \times $ election in parentheses. 
Columns (1) and (2): results within a municipality $ \times $ election (across candidates); 
Columns (3) to (6): results within a municipality $ \times $ party (across time). 
Columns (1) and (2): 2SLS estimates for candidate vote shares within municipality and election (across candidates); 
Columns (3) and (4): 2SLS estimates for candidate vote shares within municipality and party (across time); 
Columns (5) and (6): 2SLS estimates for abstention and invalid ballots within municipality and party (across time). 
First-stage F-statistic is the Kleibergen-Paap rk Wald F-statistic of the first-stage estimation with Eligible births (\%) $ \times $ Radical and 
Eligible births (\%) / $ \Delta \text{Radical} $ as the exogenous instruments. 
* significant at 10\%; ** at 5\%; *** at 1\%.
