So why are we supposed to feel any differently about Michelle...?
Yes.
She checks off some boxes that Joe doesn't and as such will attract people that Biden doesn't attract.
Her name is Obama.
She's black.
She's a woman.
Unlike Kamala, she's reasonably intelligent.
She doesn't have dementia.
Because they recognize that Kaanala-la-la garners zero respect, & is even worse than Joe Biden. Her sole purpose was to make Biden impeachment proof, period.
