Sorry but I think there are better ways to increase popular support than what you are suggesting,
Both Nixon and Ronnie Reagan didn’t fall into the types of sidelining positions you are promoting. And yes they are sidelining, meant only to marginalize her from being the relevant person she is (whether you love her, hate her or fall somewhere in between one thing everyone does, even “average Americans” is listen to her.)
Reagan was President of the Screen Actor’s Guild before he was Governor.
We can agree to disagree. I think she needs a job to help her image...President of a University ala Condi Rice perhaps. C’est la vie.
