Readiness to vote on June 9 was declared by 40% of respondents in a nationally representative survey conducted by the "Alpha Research" agency. 35 percent will vote for European Parliament because many Bulgarian communities in countries outside the EU cannot participate in EP elections.

At the beginning of the election campaign, GERB-SDS had the support of 25.4% of those who decided to vote. 17.5% are ready to vote for "We Continue the Change - Democratic Bulgaria". DPS and "Vazrazhdane" gain 14.9% and 14.6%. BSP has an electoral support of 8.5%. With 4.8% support, ITN would enter the national parliament, but they are below the threshold for entering the European Parliament. The leading topics among voters are: corruption; low incomes; healthcare; demographics; Bulgarian production and road infrastructure.
