I Think You're Mistaken

New Obama slogan has long ties to Marxism, socialism

No, not about that. Ties to Marxism and socialism have been rife throughout Obama's campaign and presidency. This is where I think the author is wrong:

The Obama campaign apparently didn't look backwards into history when selecting its new campaign slogan, "Forward" — a word with a long and rich association with European Marxism.

They know exactly the history of the symbols and words they use and they use them proudly. You may make an innocent mistake once in a while, but not every time. This is a theme with Obama, it's his thing, it's what he is. His actions match the history.
