I think I understand what she's saying, but she's saying it in the worst possible way. I think she's saying that there are the dreamers and there are those in power who recognize and support those dreams and then pass laws to make them realities. Saying that dreamers are great, but the job of the President is to not be a dreamer but someone who recognizes and supports the dreams.
But that's a clumsy argument. And I personally would rather have a Kennedy-esque President (or a Clinton-esque President) with big plans and the resolve to fight for them. The President she describes would be too willing to reconcile those dreams since they're not her own.

Bow ties are coool.
