Nick Arama writing at Red State quotes Sen. Ted Cruz (R-TX) to the effect that the only Democrat who can replace Joe Biden and get rid of Kamala Harris at the same time is Michelle Obama. Any of the other choices run the risk of offending the crucial Black vote.
The problem: Michelle appears not to want the job. The questions are these: does she want to avoid it enough to let Donald Trump be president again? Can they offer her enough to change her mind? Can they get the Bidens to go quietly?
Imagine Barack becoming chief of staff and running the government while she does the figurehead stuff - presiding at the Easter egg hunt, pardoning the turkeys, chatting up foreign dignitaries. Imagine how that would play with feminists, they'd be bleeping livid.
