Voting to get a "political product" is a sickness.
I guess Americans can be forgiven for thinking of voting as a way of paying for a "political product." It's deeply misguided, but in our world, practically everything has taken on the characteristics of a transaction.
First, the product is shown or proposed. The buyer looks over the product or proposal. The buyer chooses and "buys." The product is delivered or not. If the product is not delivered as proposed, then the buyer has a right to be angry and to choose not to buy from the seller in the future. If the product is delivered as promised, the buyer returns for more.
Fine, but voting isn't that. Government isn't that. Everything isn't that.
I think a lot of folks have gotten so used to this passive, "sell me something" paradigm that we sometimes apply it where it doesn't apply. Voting isn't buying. Voting is taking action. Voting is, if anything, producing a product, not simply buying one off of the menu.
Look at the net monetary value of a single vote. It's practically worthless. People used to—rationally—sell their votes for a beer. One of the best arguments against the Republicans' lying contention that there is widespread voter fraud is simply that a vote isn't worth enough to risk going to jail over. It isn't worth enough to risk getting a parking ticket.
A vote isn't money, and you aren't buying things with it. And if you don't get the things you thought you were "buying," you don't have grounds to be angry. You weren't buying anything. You were trying to empower a position. You don't get to be a consumer in this case, much as you might want to be. Much as you might not be able to see yourself as anything else.
A voter is just a tugger on a rope, an engine on the democratic plane, not cargo. If you don't win the tug-of-war or the plane doesn't make it over the mountain, it doesn't mean you didn't "get what you paid for." It means that voters with your position—as a group—were outnumbered or, if not outnumbered, failed to do their part.
