Non-cola-likers have always fared better with protest demonstrations, news media publicity, and rights-based lawsuits. Voting has done nothing.
With the entrenched structure of the system in place, any issue that is not likely to switch your vote from Coke to Pepsi, or vice versa, can be safely ignored. Don't like that much sugar/HFCS? Ignored. Don't like carbonation? Ignored. Don't like caramel color? Ignored. Don't like phosphoric acid? Ignored. But if you like Cherry Coke better than regular Coke, well then Pepsi might just trial-run a Lemon Pepsi! Do I vote for that because it is closer to grapefruit juice than anything else on the ballot, or not vote for it because it's still just another falalahking cola?
The only group likely to make even a tiny dent in the status quo of Beverageland is the people who like coffee. But coffee never stands for election. Nobody ever even considers that coffee might be better than any cola. What does this mean metaphorically? I don't know; it ran away from me there.
That is why it is important to be an influence with the vote.
I never pull the party lever but I also know local politics really is the foundation for our political system and if you like Cherry Coke let your local politician know what you want. Heck follow them on FaceBook and talk with them.
