Robert Novak is reporting that “according to Democratic sources, former President Clinton got Steven Spielberg to step away from a tacit endorsement of Sen. Barack Obama. Spielberg has let it be known that he will host a future fundraiser for Clinton” — Bill or Hilary? — “as part of a policy of helping all Democratic presidential candidates. But Jeffrey Katzenberg and David Geffen seem to be clearly in Obama’s camp.” Let no one ever accuse Spielberg of lacking backbone or principle. A little massaging from an ex-President, some smiles and choice words and wham…he’s on the fence.
