I don't think that's to much to ask especially since i'm sure that Clay took the time to educate himself on what the laws were and also know what his rights were before he went to the polling place to exercise his right to vote while legally carrying his firearm.I doubt anybody is suggesting that cops or poll workers or anyone involved should (or even could) know all the laws, but how about knowing the one you're currently attempting to enforce?
Would that be asking too much?
