%description
Provides tools to download datasets of German elections covering local,
state, federal, mayoral, European Parliament, and county (Kreistag)
elections, with federal county-level coverage from 1953 and other families
extending through 2025. The package supplies turnout, vote shares, and
derived indicators at the municipal and county level, including
geographically harmonized datasets that account for changes in municipal
boundaries over time and incorporate mail-in voting districts. Bundled
data includes county-level INKAR covariates (1995-2022) and
municipality-level Zensus 2022 indicators. Data is sourced from
<https://github.com/awiedem/german_election_data>.
