Me thinks the numbers won't be so bad if you add splinter green and left parties, although there is a real shift of social democrats to traditionally liberal economics in Europe.
At least there's a chance for social democratic revival in Canada.
Also social democrats in Latin America are currently at a peak.
Alas I think the social democrats in South America habe begun to peak and are collapsing in on themselves. Rousseff, Bachelet and Kirchner are all mired in corruption cases and subpar approval ratings; while even the hard left leaders seem to be encountering some sticky problems.
