I knew that sounded awfully familiar. From Wikipedia:
Vorwärts (“Forward”) was the central organ of the Social Democratic Party of Germany published daily in Berlin from 1891 to 1933 by decision of the party’s Halle Congress, as the successor of Berliner Volksblatt, founded in 1884.Vorwaerts lives on today as the house organ of Germany’s leftist SPD; you can read all about its illustrious history here (in German).
and Kurt Tucholsky both wrote for Vorwärts. It backed the Russian Marxist economists and then, after the split in the Party, the Mensheviks. It published articles by Leon Trotsky, but would not publish any by Vladimir Lenin. . .
And if you don’t think David Axelrod doesn’t know this, you really ought to think again.
Victor Morton at the Washington Times also has a story on the Marxist slogan.
