Dasmariñas City used to be part of Cavite's second congressional district until June 30, 2010. The city has now its own legislative district, although that district is still part of the representation of Cavite (Cavite's 4th legislative district will also be known as the Legislative District of Dasmariñas. It is also the second largest component city in terms of population (556,330 as of 2007), next only to Antipolo. Such population is enough to warrant Dasmariñas another congressional district, and by then deem it independent from the representation of Cavite if the move prospers.
