Govt Approval Rating Down to 20.9%
According to the poll, the SD, which was trailing the SDS in the last two months, is ahead with 12.1% to 11.8%.
Support for the ruling Positive Slovenia (PS) in third place has increased slightly to 5.6% despite the tensions ahead of the party's election congress.
The Pensioners' Party (DeSUS) follows among the parliamentary parties with 4.6%, New Slovenia (NSi) with 3.2% and the People's Party (SLS) with 2.4%.
As many as 73.6% of the respondents said the government was doing a bad job, which is an increase from 68.3% in March.
The 20.9% support rating is the lowest for the incumbent government, but not a record low - the 2008-2011 Borut Pahor-led government even fell below 10%, while the lowest point for the 2012 Janez Janša government was 13.6%.
People's lack of trust in politics is also reflected in an increase from a quarter to a third in the share of voters who said they would not attend the 25 May EU election. The share of undecided voters or those who do not plan to attend the national general election stands at 56%.
Meanwhile, President Borut Pahor has reclaimed the top spot in the politicians' rankings from Agriculture Minister Gregor Židan, who overtook him last month.
The pair are followed by EU Environment Commissioner Janez Potočnik, Foreign Minister Karl Erjavec and Prime Minister Alenka Bratušek.
The poll was conducted by Ninamedia between 15 and 17 April on 700 respondents.
