I'd be ok with every state banning hunting over bait, probably because I grew up in a state where it wasn't allowed until 2006, and then only in urban areas. I'm sure that this would upset many other hunters, though banning hunting over bait is very popular with many non-hunters and is probably the wave of the future.
However, if you analyze the many variables and possibilities of a total food plot ban it quickly becomes clear that it would be almost impossible for a state to ban planting food plots for deer, and/or for the state to also ban hunting over said food plots for deer.
How could a government entity ban planting a legal food crop like corn, no matter what the end purpose would be for the grain? Or just ban planting corn if there's a chance that a deer might eat some? Or ban hunting within 500 yards of anything that a deer might eat? Or ban hunting beside a field only if the crop was planted with the intent of attracting deer to shoot them?
As these examples show, it's almost impossible to legally differentiate between a wildlife food plot and a farmers crop field, and also, a very large percentage of hunters hunt within a deer's reasonable travel distance to a crop field.
The main hunting regulation that many states have regarding hunting over food plots is that the crop may not be manipulated in any way to draw wildlife, in other words, here in Pennsylvania if you shell one ear of corn that's growing on the stalk in front of your hunting blind you already broke the law, as many people have had to learn the hard way. And if someone commits this ear corn shelling infraction while goose hunting it becomes a federal offense, which has higher penalties and stricter courts.
So, I don't think that you need to worry about food plots being banned anytime soon.
