Austria goes to the polls on the 15th. In past decades, Austria has had very routine and boring politics. After WW2 an "all party coalition" was formed between the OVP (the Conservatives), the SPO (the Socialists) and the KPO (the Communists). After dropping the Communists from this arrangement, the OVP-SPO kept in coalition until 1966, when the OVP formed a single party government, which was replaced by a single party SPO government in 1970 which ran until 1983.
At that time the Socialists decided to coalition with the FPO, or Freedom Party. At the time the FPO was more centrist and Liberal, however Jorg Haider rose up in the party and turned the FPO into a vehicle for nationalism.
Finally, in 1986, the coalition was restored, and was maintained until 1999, when OVP formed a coalition with FPO. While Haider himself was not included in government, EU countries imposed some sanctions on Austria. When it became clear FPO was not a threat to democracy, those sanctions were lifted.
In 2006 the traditional SPO-OVP coalition was restored, and has been governing austria since.
In the last election, in 2013, the SPO took 52 of the 183 seats, compared to 47 for the OVP and 40 for the FPO.
Until this spring, polls indicated the FPO on course for victory with the SPO in second, however the election of a new OVP leader over the summer, Sebastian Kurz, has changed that. Polls have shown a very consistent and nearly flat line for the OVP at 33% support, ahead of the SPO at 23% and FPO at 25%.
OVP - Austrian Peoples Party.
This is the "Conservative" party in Austria and has strong christian democratic roots, it is often compared to the CDU in Germany. It is a moderate right party with a long history in government and is expected to win the election.
SPO - Socialist Party of Austria
This is Austria's answer to Germany's SPD. It is the main left-wing party in the country and is currently leading the government. Polls indicate it will do poorly, perhaps even finishing third overall.
FPO - Freedom Party of Austria
This party has become more anti-immigration and anti-islam over the years and now presents an extreme viewpoint on the issue. It is in line with people like Marine Le Pen and far exceeds Donald Trump on opposing immigration.
The current President of Austria was Green leader for many years, but the party has fallen on rough times as one of its members has quit to create a splinter party. This party is like any other common 'default' Green party that can be found in Europe
Peter Pilz List
Started by a former Green, this party focuses on corruption issues and democratic reform. Its main planks are support for transparency and opposition to unethical behavior.
NEOS - New Austria Liberal Forum
This party polled well in 2014 but has since fallen in the polls and is now at or near 5% as are the two other "smaller" parties in Austria at the current time. They are a Liberal and pro-europe party.
Current polls, which are mostly stable, suggest the following result:
63 - OVP
50 - FPO
43 - SPO
9 - Green
9 - Pilz
9 - NEOS
It is unknown, however, if OVP will chose FPO or SPO for their coalition partner, as both comes with their own risks.
