Political process
The electorate
National elections to the Bundestag are held once every four years. All German citizens at least age 18 are eligible to vote (this was reduced from age 21 in 1970), and 16-year-olds are eligible to vote in municipal elections in some Länder. In 2011 Bremen became the first Land to extend suffrage to 16-year-olds for state elections. The Basic Law established a mixed electoral system, consisting of elements of both plurality and proportionality. Half of the Bundestag’s members are elected to represent single-seat constituencies, and half are elected through proportional representation. Voters cast two ballots. Constituency representatives are elected by the distribution of votes on the first ballot; the candidate winning the most votes secures election to the Bundestag. Voters cast ballots for political parties at the regional level with their second vote (Zweitstimme), which determines overall party representation. A party must win at least 5 percent of the national vote (or win at least three constituencies) to secure representation, and the number of seats it is allocated is based on its proportion of second votes. The system is designed to simultaneously provide a link between citizens and elected representatives and a legislature that reflects a consensus of opinions in the country. Bundesrat members are appointed by the state governments, and the body exercises its authority to protect the rights and prerogatives of the state governments. Each state is allocated between three and six members of the Bundesrat, depending on population.
The quadrennial general and provincial elections as well as local elections are attended with the greatest interest and involvement by the electorate. The public is kept informed on political issues through intense media coverage, and political affairs are frequently debated among German citizens. Although voting is not compulsory, the participation rate is high, with about three-fourths of eligible voters casting ballots. Since elections in the states are staggered throughout the life of each Bundestag, they act as a bellwether of public opinion for the incumbent federal government. German citizens, along with German residents who are citizens of other EU countries, also elect representatives to the European Parliament, although voter participation in these contests tends to be lower than in general or state elections.
