That's as of today. Public opinion will change over time.
In a few weeks, say some time in May, we'll start getting back toward normal. Folks will go back to work, more and more as the month progresses. Restaurants will open for dine-in again, perhaps with lower capacity and spaced seating. States will go back to holding election primaries. You'll be able to easily find toilet paper because people will realize this isn't actually the zombie apocalypse (and the worst offenders' attics will be so full of TP they can't fit any more).
A month later, in mid-June, the news will no longer be focused on corona virus to the near-exclusion of everything else. Consequently, we'll hear about, think about, and have conversations about, other things. Covid-19 will begin to fade into the background, maybe not quite as much an after-thought as the flu, but heading in that direction. Everyone will be eager to get back to work, and restrictions will ease up even more.
By mid-July, people will start going on vacation, just like they used to. Seaside towns will no longer turn them away, business will be booming, the whole covid-19 scare will start to feel less like something we're living through and more like something that happened to us. It will move from "present" to "past".
By early August, the NCAA and its member institutions will agree that it's okay to hold fall camp.
In September, the football season will likely begin. Maybe as late as the start of October, but probably September. Maybe on original schedule, even.
At that point, the 72% who said back in April they wouldn't attend without a vaccine, they'll be significantly less worried. Covid-19 will be in a wider context by then.
Things are going to be okay. Let's just take it one step at a time, but we're turning the corner.
Go Vols!
p.s. Of those 72%, most don't attend football games in person anyway. The pollsters should have restricted the question to those who do normally attend games.
