Overview

This tracker records the comparable nationwide party-vote polls available for Bulgaria's published election period. The archive is short and election-specific, so it is presented as a bounded body of evidence rather than a continuous long-term measure.

Electoral system context

National Assembly members are elected proportionally from multi-member constituencies, with a national threshold for ordinary parties and coalitions. District allocation, votes for lists below the threshold and the separate treatment of none-of-the-above responses affect how published support relates to seats.

Party and bloc rationale

The local balance groups the published PB, BSP and PP–DB keys against GERB, Revival, DPS, ITN and MECH, while APS, Velichie and others stay outside. The grouping is a Bismuth navigation aid for this period, not an official coalition or international ideology ranking.

Polling limitations

Repeated elections, party splits and coalition labels make cross-cycle comparisons unusually fragile. The small number of rows magnifies individual pollster differences, and national values cannot reproduce constituency allocation; unsupported dates, missing parties and disputed source changes are not filled or silently accepted.
