Perwakilan berimbang

Sistem proporsional terbuka adalah sistem perebutan kursi di parlemen pusat dalam satu pemilihan umum sesuai dengan proporsi suara yang diperoleh partai. Kelemahan sistem ini adalah calon-calon kurang dikenal oleh konstituen karena wakil rakyat ditentukan oleh partai, sehingga program yang ditawarkan adalah program partai bukan program calon.
