New “political” spam

There’s a new wave of political spam hitting mailservers across Europe and presumably the globe.
Most of it seems to be in German, though some subject lines in English have been reported.
It looks like they are being sent by zombie PCs.
This is very similar to the nazi spam which was spotted about 14 months ago.
Update: Raymond has released an SA ruleset to block most of this junk which has been identified as being sober related
You can grab the ruleset from :

I’ve added that to some of our servers and it’s working nicely
