Bulgaria's electoral system gives no seats to parties under the 4% threshold. Votes cast for those parties end up with no representation — what we usually call "wasted votes".
What you'll find
Wasted nationally — total share of votes cast for sub-threshold parties.
Almost made it (2–4%) — parties that came close to passing.
Fringe (<2%) — fragmented "margin" votes.
By region — choropleth map plus sortable table by multi-mandate region. See the full regional ranking.
Calculation: sum of votes for parties below the 4% national threshold, divided by total valid votes.
