So, does the move toward Anel signal that a Grexit is more likely or less likely than first thought?
It is more to convince the Germans that they might really be crazy, in order to extract more concessions. Not sure this will work since giving concessions to the Greeks would probably trigger demands from other beleaguered southern economies for similar relief.
The CDU probably wouldn't want to lose any votes to the AfD too, which could happen if it looks the Greeks are given too much leeway. On the other hand, it isn't really an important election year with state elections happening only Hamburg and Bremen. 2016 would be much tougher.
