Via Open Europe, this is an interesting twist:

There’s a school of thought out there – usually fairly uninformed – which has it that a German government that features the SPD (social democrats), could fairly effortlessly strike a deal with Francois Hollande over further fiscal integration, which would include, for example, eurobonds and greater ECB intervention. People arguing this point notes that SPD supports eurobonds, while doing fairly well in opinion polls. That should cut it right?
Well, this view tends to underestimate the German cross-border consensus on sound money and budget discipline. And from today’s Die Welt we learn that the SPD has retreated from its previous support for Eurobonds, thereby distancing themselves from their French counterparts. Thomas Oppermann, the party’s speaker in the Bundestag said:
“We oppose the uncontrolled pooling of debt… There is absolutely no need for general eurobonds”.
Oppermann added that:
“I speak for [Germany] and not for France”.

Good for him.
