And notably it wouldn’t just be a decree from on high, it’d be officially picked by the delegates. There was still (technically) a primary this year, with delegates heading to a convention to vote on who becomes the nominee. I’m sure there will be a lot of backroom plotting to try to figure out a good replacement before the open votes start, but at least there’s an air of legitimacy as (many of) the people who officially make the decision have some connection to votes cast. It’s more an appearance thing than actually separating the pick from “the party establishment”, but that’s a pretty important aspect.
