%description
Provides tools to download comprehensive datasets of local, state, and
federal election results in Germany from 1990 to 2021. The package
facilitates access to data on turnout, vote shares for major parties, and
demographic information across different levels of government (municipal,
state, and federal). It offers access to geographically harmonized
datasets that account for changes in municipal boundaries over time and
incorporate mail-in voting districts. Users can easily retrieve, clean,
and standardize German electoral data, making it ready for analysis. Data
is sourced from <http://www.german-elections.com>.
