It’s hard to think of a better way to galvanize Trump-skeptical Republicans for the 2020 vote than to preemptively announce a Democratic court-packing agenda for 2021. If law professors hadn’t started vowing that the next Democratic president would “pack the court,” then a pro-MAGA Super PAC would have made it up.
As Insty has said, for 2020 all the Democrats had to do is not be crazy; and they can't do it.
