One of the better reads, that I have seen, on GA voting law

The "but no water" thing blew up on Twitter. I have yet to understand how it is even a bone of contention. Here is what it says:
Another section of the law, which has generated criticism from Biden and others, limits how voters can be provided food and drink in the vicinity of a voting location. The law makes it a misdemeanor for "any person" to give or offer "any money or gifts," including "food and drink," to any voter within a polling place, within 150 feet of the building housing a polling place, or "within 25 feet of any voter standing in line to vote at any polling place."
This provision is located in the same paragraph as a provision banning campaign activity in these locations, but the provision doesn't prohibit only people who are campaigning from giving out food and drink. It says "any person," not just campaigners.
There is, however, one exception: poll officers are allowed to make available "self-service water from an unattended receptacle to an elector waiting in line to vote." And it's perhaps worth noting that there is not a prohibition on voters in line buying food and drink for themselves; the provision is about other people providing "money or gifts" including food and drink.
