It's a joke. Notionally, when you ask a child what he wants for a
present, he will ask for a pony, being a child and not having any
sense of what is practical. By extension "asking for/promising a pony"
refers to naive and unrealistic demands: "Everything you asked for, no
matter what that might be, and more."
Hence: Congressman X promised peace, prosperity, national greatness,
and a pony.
