Influence

If the current claim is that getting millions of dollars from special interests, in the form of speech payments and donations and other dark money does not, can not, will not, influence her policy decisions, does not for anyone she associates with, then why is she against Citizens United?
Why is Koch and other corporate money bad for republicans if money can never influence politicians? If it would never influence her than why won't she keep making millions of dollars giving speeches to Goldman Sachs if she becomes president? Then put all that money directly in her campaign fund for her next election? Why limit what people can contribute or do with it? Clinton says it doesn't influence policy?? Based on her comments and position it is hard to understand why she is against Citizens United. Money never influence policy or political outcomes as far as she is concerned.
