This is perfect. Hillary isn't up to campaigning. She will need to use various stocking horses to deliver the words of her campaign, but the public will want to hear it from her. Ultimately the Presidential candidate debates will become huge and in them Trump will be Trump and say things that Hillary doesn't want to hear or deal with. At that point she will refuse to address the issue are make a snide comment and loose public support.

a political candidate who runs only in order to provoke the election and thus allow a stronger candidate to come forward.
