Electoral district of Sierra

Sierra is an electoral district of the Enderronian Parliament in Sierra Prefecture. It was created in 1946 and first contested at the federal election later that year. It covers the entire prefecture of Sierra, and is the largest electoral district by land area in Enderron.

The sitting member, since the 2002 federal election, is Vince Stanton, a member of the Enderron National Party.

History
Historically, Sierra was split between strongly pro-Social Democrats territory in the urban areas like the capital Los Prados and the mining regions, and more conservative-leaning areas in the agricultural plains. Through the early post-independence years, the United Party's overall dominance of nationwide politics gave it a slight edge in Sierra and allowed it to hold the seat continuously from 1946 to 1970. Sierra was lost to the SDP when the United government was soundly defeated in 1970. Left-wing independent Brian Callister won the seat in 1974 and held it until 1982.

The National Party has held the seat continuously since 1995, and has come to dominate Sierra at the federal level. It is now the party's safest seat, with a 22.89 percent swing required to lose it. However, most political commentators regard Sierra as being less safe than its margin implies, due to several unique features of Sierran politics: Sierrans tend to vote for particular candidates, especially community-based and incumbent members, rather than along political lines. Therefore, sitting members are usually not defeated, and large swings can occur when sitting incumbents retire.

Since the 2000s, the centre-right Liberal Party has often declined to run candidates in the seat, in an unofficial agreement between the local Liberal and National branches.
