Re: "Concerned Citizens of Alabama"
Labelling helps in the sense that if you haven't heard of the group you can assume that it *is* just a front for some money that doesn't want you to know who they are. That, in the mind of any intelligent voter, is enough to make the content ignorable. This line of reasoning is even automatable: you whitelist the (few) organisations that you do recognise and simply ad-block the rest.
But if you are minded to do any of that, you are probably already using my preferred algorithm for dealing with political ads, which is to whitelist none of them. Any group with anything useful to say has had the years running up to the election to say it. Voters really *ought* to ignore *all* political advertising in the run-up to an election.
