Quite honestly, I can't take that article seriously. With the current trend in the series in terms of the types of women they hire for the Bond girls (i.e. young, up and coming actresses), there's no way that they're going to go in the complete opposite direction and hire a politician with no acting experience to headline the next film in a series that just saw a film earn $1 billion at the worldwide box office.
As for Scorsese, he's far too busy for Bond at the moment, especially if pre-production on Bond is slated to begin sometime during 2014. He currently has several projects in various stages of production, according to IMDb: The Third Side of the River (executive producer - post-production); Malavita (executive producer; post-production), The Wolf of Wall Street (producer/director; post-production), Life Itself (executive producer; filming), Revenge of the Green Dragons (executive producer; pre-production), Tomorrow (executive producer; pre-production), Untitled Bill Clinton Documentary (director; filming), Silence (director; pre-production), and Sinatra (producer/director; announced).
