I'm not sure what "huge list of assumptions" you are referring to, merely the idea that she knows this can't pass today? I think putting these ideas out there in concrete form is a fine approach. If she wanted to "pander to the media" she could have just come up with a slogan with nothing behind it. An actual proposal that can be debated is the opposite of pandering to the media. "Repeal and Replace" as the entirety of your proposal is pandering to the media.
