Bush was clearly the face man of an executive admin that he didn't run, he was s figure head. Clinton, it was assumed by the press and a lot of the voter base wasn't running his admin, the first term Hillary was said to be running things and a slew of technocrats was assumed his second term, Reagan, we now know historically, was experiencing Alzheimer's all through out his presidency, much like Trump, he also had a strict schedule of not even pretending he showed up to work.
There's nothing wrong with electing the face of an administration you want in office, this is largely Obama's admin still running the government, that's what we all want. Unkie Joe can take all the naps he wants, it make no real difference.
