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.
Now, sure. After the midterms... Maybe a different story (at least in terms of getting it to President's desk), depending on how they turn out.
Sure, not all of it will survive the process, but if the only substantive restriction that accompanied the charter was the political spending rule, Democrats would love to put Trump in the position where he'd have to either sign or veto that.
I doubt she expects it to pass. I suspect she does hope it will help the dems win a few seats in the next election.
