About this election
The political system
Portugal is a semi-presidential republic. Voters elect the 230-member Assembly of the Republic (Assembleia da República) for four-year terms by proportional representation, using the D'Hondt method across 22 multi-member constituencies — the 18 mainland districts plus the autonomous regions of the Azores and Madeira and two constituencies for citizens abroad. There is no national threshold, but D'Hondt and the small size of many districts favour larger parties. The Assembly's composition determines who can form a government; the directly elected President, a separate office, appoints the prime minister and can dissolve parliament but does not run the executive. This division of powers would prove decisive in 2015.
