BERLIN (AP) — Germany's governing parties made an unusual show of solidarity with their main challengers Thursday by denouncing an advertising campaign targeting the environmentalist Greens. The ads that appeared on posters in dozens of German cities less than two months before the country's national election feature a wilted version of the Green party's sunflower symbol, phrases such as “climate socialism” and “eco terrorism,” and the hashtag #GruenerMist, which means “Green Garbage.”
