Why don't they sell hard liquor in grocery stores in Virginia?

my guess would be cause the are in the bible belt as people call it in the south and allot of southern states have blues laws i live in south carolina and they can not sell beer and liqueur in the same store and you can not buy it on sundays here that is the way it is in the south the churches have allot of pull in south south carolina is just now making where you can shop on sundays at any time before it used to be you could shop till after 1:30 pm its the blue laws my best guess
