Steffen Bilger sits in the Bundestag as the directly elected member for Wahlkreis 265 Ludwigsburg. This page looks at the institution behind that title: what a constituency is, how it is won, which towns it contains, how its results have moved since 2009 and what a constituency MP actually does between elections.

What a direct mandate is

The German electoral system combines MPs elected by name with seats distributed through party lists. The 299 constituencies are the part of the system that ties a member of parliament to a specific place.

Each of the 299 federal constituencies (Wahlkreise) is drawn to contain roughly the same number of people, and the boundaries are reviewed by an independent commission before each election. In each one, parties nominate a single candidate, chosen by their local members or delegates. On election day voters use their first vote (Erststimme) to choose among these named candidates. Whoever receives the most first votes wins; there is no run-off and no minimum share.

The second vote (Zweitstimme) for a party list determines the overall strength of each party in the Bundestag. Until 2021, a party that won more constituencies in a Land than its second votes justified kept the extra seats as overhang mandates. The 2023 electoral reform ended that: the Bundestag now has a fixed size of 630 seats, and a constituency winner takes the seat only if the party's second-vote result in that Land covers it. In February 2025, 23 constituency winners across Germany did not enter the Bundestag for this reason. Ludwigsburg was not among them.

A direct mandate is legally identical to a list mandate; a member elected in a constituency has exactly the same rights in the Bundestag. The difference is political. A constituency MP has a defined area, a personal vote that can run ahead of or behind the party's, and an expectation from local people that he or she will be available to them. For an analysis of how the mandate fits into Bilger's career, see the Bundestag career page.

Two things stand out. The electorate grew by about 8,000 between 2013 and 2017, the election at which Weissach joined the constituency. And Bilger's vote has been more resilient than his margin: in 2021 he lost 16,000 votes on 2017 but still won by more than nine points, with the remaining vote split among several parties.

04 · History

The seat since 1949

  1. 1949No. 3The old Landkreis Ludwigsburg, before the district reform.
  2. 1953–1961No. 165Same area, new number.
  3. 1965–1976No. 167Redrawn for 1976 to a list of Ludwigsburg-district towns.
  4. 1980–1998No. 169Today's fifteen Ludwigsburg-district municipalities.
  5. 2002–2005No. 266Renumbered after the Bundestag was reduced to 299 constituencies.

Until the mid-1970s the seat changed hands between the SPD and the CDU. Since Matthias Wissmann's first win in 1976 it has stayed with the CDU. Wissmann, federal transport minister from 1993 to 1998, later became president of the German Association of the Automotive Industry (VDA); in 2018 ARD’s Monitor programme mentioned Wissmann when it reported on a motion from Bilger's CDU district association, Nordwürttemberg, against the Deutsche Umwelthilfe; see the criticism page.

Constituency work

The Bundestag sits for about twenty weeks a year. The rest of the time a constituency MP is expected to be at home.

Every member of the Bundestag receives an allowance to employ staff and run offices, and most directly elected MPs keep at least one office in their constituency. Bilger's is in Ludwigsburg, on the Stuttgarter Straße. Such offices handle letters and emails from constituents, arrange appointments and visits, and keep in touch with local councils, firms, associations and party branches. For constituency MPs generally, a week outside Berlin typically includes visits to companies and institutions, local party meetings, events of associations such as the CDU seniors' organisation pictured on the Ludwigsburg page, and public question-and-answer sessions.

Bilger has spoken about this side of the job in the plenary. On 16 September 2025, as First Parliamentary Secretary, he defended shorter debating times during a budget week. According to the Bundestag's report, he argued that a shorter Friday schedule gave members time for their constituencies and their families, since the Bundestag was sitting three weeks in a row that September.

The constituency also feeds into federal work in less visible ways. Local concerns about a motorway junction, a rail line or a company's future can become written questions to the government, letters to a ministry or points raised inside the parliamentary group. Bilger's voluntary roles listed with the Bundestag reflect local ties: he sits on the board of trustees of the Ludwigsburger Schlossfestspiele, the city's classical music festival, and was until 2021 a member of the supporters' circle of the MHP Riesen Ludwigsburg basketball club.

Since July 2026As Federal Minister for Transport, Bilger keeps his seat and his constituency. Ministers who are also MPs remain bound to their constituencies, but their time there is inevitably reduced. How he divides it is not documented in the sources available.
