With hardly more than a month to go until the general elections, Hungary’s main opposition Fidesz maintained its lead over the ruling Socialists last week, a recent poll by the Nezopont Institute showed.
The poll conducted on a sample of 1,000 over-18 respondents from March 5 to 7 indicated that support for the three parties generally tipped to win seats in Hungary’s next Parliament had not changed considerably as against the previous week.
Forty nine percent of respondents willing to vote expressed support for Fidesz, 12 percent for the Socialists and 9 percent for the radical nationalist Jobbik party.
The poll, commissioned by the weekly Heti Valasz, suggested that neither the conservative Democratic Forum, nor the green LMP would be able to clear the 5 percent threshold required for acquiring seats in Parliament.
Twenty six percent of those asked were unable or unwilling to tell whom they would vote for.
In the six weeks to the early March poll, support for Fidesz fluctuated between 42 and 51 percent. The corresponding bands were 10-12 percent for the Socialists and 7-9 percent for Jobbik.

Why such a disparity between this poll and the ipsos poll? Does anybody know which is the more reliable pollster?
