According to politics.hu, the Hungarian Socialist Party is committed to forging a broad pre-electoral alliance in order to defeat the ruling Fidesz in the 2014 general elections.
The Socialists committed themselves to entering joint lists for the election last November. A week ago, however, E14-PM ((ex-PM Gordon Bajnai’s faction.)) raised the idea of coordinating whom to nominate in individual constituencies but fielding separate lists.
The Socialist board confirmed, however, that setting up a common list would offer the biggest chance for a change in government.
This is a reminder that the Hungarian electoral system is not MMP. Since the first post-Communist election of 1990, it has been a fundamentally majoritarian mixed-member system. It became even more so with recent reforms.
Fruits and Votes 
What the Hungarian Socialists are planning on doing is the same thing the old Concertación is doing in Chile, creating a new electoral alliance called New Majority, including the Communists for example.
Assuming they do go on to present a united front, what are their chances of unseating Fidez (however it is spelled)? I was under the impression that Fidez doesn’t have much chance of losing its majority.
I can’t answer the question of how popular Fidesz is, but they won only 53% of the vote in 2010. The Socialists had only 19% (list vote). So a unified opposition could stand a chance–assuming there is discontent with the current government’s authoritarian bent.
Of course, the Socialists aren’t going to form a front with Jobbik, which won 17%.
(And, it is Fidesz. Without the z, the Hungarian pronunciation would be “Fidesh”, which sometimes is how it is pronounced by Western news media. But the final sound is just an ‘s’.)
