@Gehenna discussed seeing this in polling before. When asked about vaccine mandates in general, people were more or less supportive. As soon as you brought up enforcement mechanisms, support
plummeted. Now, I don't really know why people would be supportive of a mandate without any way to enforce it as it'd be pretty much useless theater, but it turns out that most people don't actually want to see people fired over this shit.
Now that the consequences of this retarded EO are being seen and felt nationwide, I'd expect support to drop even further. Hilarious that this is all happening before any actual regulations have been created, so all these businesses/corporations are putting themselves through hell for virtually no reason (although the info that they're concerned about retroactive mandates makes this make a little more sense, kind of).
