Senate The new constitution restored the
Senate and its
plurality block voting system in use from 1941 to 1972. In this election, all 24 seats are up, and the winners' terms will start in June 30, 1987, and end five years later.
House of Representatives The new constitution reverted to the House of Representatives, in use from 1935 to 1972. Unlike its original iteration, the House now adopts the
additional seats reserved for sectors first applied in the
Batasang Pambansa. There are now 200 districts from
congressional districts, then 20% of the seats will be reserved for the
party-list system; in lieu of the adoption of such a system, the constitution allows for the old sectoral representation from the Batasang Pambansa to be continued. == Campaign ==
