Taking place April 27th.
A Gallup poll on April 1st shows:
Progressive Party (anti-EU liberals) 28.3%
Independence Party (formerly dominant conservatives) 22.4%
Social Democratic Alliance (incumbent centre-left) 15%
Bright Future (ideologically vague party with two incumbents, a former Social Democrat and a former Progressive, as well as links to the joke-y Best Party) 12.7%
Green-Left Movement (left-wing junior partner in the current coalition, came close to coming in second last time) 8.5%
Pirate Party 4.4%
Democracy Watch (breakaway from Dawn, see below) 3.1%
Right-Green Movement (low tax greens) 2.1
Dawn (Vague anti-establishment populists who did moderately well in the last election under the name Citizens' Movement) 1.5%
http://en.wikipedia.org/wiki/Icelandic_parliamentary_election,_2013 Anti-EU sentiment seems to be the main thing helping the Progressives (who only recently switched to an anti-position).
I also suspect this is another case of the people in power being unfairly blamed for not magically fixing the economy.
I'm unsure exactly what the Progressive Party's current ideology is. They had previously been firmly on the center-right, acting as the junior partner to the Independence Party for more than a decade. Then again, they flipped on the EU, they may have flipped on more. Wikipedia says they got a party switcher from the Green-Left. As a social democrat, I'm not optimistic though.
