Electoral district of Sunnyvale

Sunnyvale is an electoral district of the Enderronian Parliament in Westhaven Prefecture, first contested at the 1986 federal election. It draws its name from Sunnyvale, the most populous city in Westhaven, and covers its central business district and surrounding inner city areas. It was formerly named Summer Coast, but was renamed after the city changed its name in 1985.

The sitting member, since the 2018 federal election, is Ivan Hawthorn, a member of the Social Democratic Party.

History
Although Sunnyvale was created in 1986, it is essentially a renaming of Summer Coast, which was created in 1946. Summer Coast was a fairly safe Social Democratic seat, being held by the party for all but one term from 1946 to 1986. The seat has become far less safe for the SDP since the 1980s, due to gentrification and demographic change, and is regarded now a marginal seat.

Since 1986, Sunnyvale has been what analysts have called a "late bellwether", as the seat changes hands between parties exactly one term after each change in government – 1994, 2006, and 2018.
