Overview

The Greek archive records published nationwide party support for parliamentary elections across changing party systems and electoral rules. Poll rows remain the evidence; summary groupings and trends are descriptive tools and do not calculate a majority or governing arrangement.

Electoral system context

Parliamentary seats are allocated through a proportional framework with an eligibility threshold and, under the current law, a graduated bonus for the leading party. The votes of parties below the threshold and the leading party's share affect allocation, so polling percentages do not translate linearly into seats.

Party and bloc rationale

The local balance groups SYRIZA, PASOK, KKE, Course of Freedom and MeRA25 against New Democracy, Spartans, Greek Solution, NIKI and other current right entries. Several historical or unaligned keys remain excluded. This is time-bounded local navigation, not an official classification.

The current source-cycle right-side set is ND, Spartans, Greek Solution, NIKI and Voice of Reason. Historical XA, ANEL and LAOS series are outside this definition. Spartans remains included when recorded: a poll that omits it cannot support the complete balance.

Polling limitations

The party field and election law have changed across the archive, and pollsters differ in whether they publish raw intention, adjusted estimates or undecided voters. Values near the threshold require caution; historical keys are not merged automatically and gaps are not bridged by synthetic trends.

Bloc summaries use complete paired polls within 45 days of the latest archive record, weighted by recency and sample size. Both sides use the same eligible polls. The tracker and map show the number of complete polls and their supporting date, which can precede the latest archive record; missing parties are not assigned zero. The comparison’s latest-poll balance is a separate individual observation.
