The ruling Fidesz-Christian Democratic party alliance in July maintained its lead both across the whole sample and among decided voters, according to a poll by the Szazadveg Institute.
Fidesz commanded the support of 23 percent of voting-age adults compared with 13 percent for its main rival, the Socialists, the institute said on Tuesday.
The poll, which canvassed a representative sample of 1,000 adults between July 20-26, found the opposition LMP party was backed by 6 percent, radical nationalist Jobbik by 11 percent, and the Democratic Coalition (DK) by 2 percent of the electorate.
Fidesz had the support of 41 percent of decided voters against 24 percent for the Socialists.
Jobbik had 21 percent, LMP8 percent and DK 3 percent, the poll found.
Forty-six percent of respondents were committed to casting ballots while 43 percent were unsure which party to support.
