At the end of the day, a lot is also in the messaging and the message it sends people, particularly those who tend to be on her side of things. And because that messaging isnt as firm, with a formal "stay at home" order, it causes less to heed it.
That's not to say that there isnt an improvement over baselline. We've seen
drops in mobility. But we've also seen less than say..
our neighbors to the north,
or to the east who have had more formal orders that sent a more firm message.
Of course people will bring up anecdotal stories of people not heeding it even in states with a stay at home order, but the data shows that that happens less in states that went fully onboard with this awhile ago.
