Two votes could cost me a hundred grand.
My town recently had an election to fill a vacancy among the selectmen. Three selectmen make town policy -- there is no mayor -- so they have a lot of power. They especially have a lot of power right now because they are debating two moronic and extremely expensive proposals that will waste taxpayer money. (One is building a desalinization plant, although we are in New England and our occasional summer water shortages are addressed easily by restricting the watering of lawns. The other is to install sewerage in an already developed town in which, in my opinion, waste disposal is quite effectively handled by a private property septic approach.)
On to my main point. . . .
The election ended in a tie. After a non-controversial recount, Candidate X won by two votes (and I think he was the one who supported the cockamamie proposals mentioned above.) If my wife and I had voted, Candidate X would have lost. If X called for a recount, there would have been a tie, and then another election in which X might have lost (I'm sure the turnout would be higher!) If I could have convinced some of my non-voting neighbors to support Y in the first election, X would have lost and that would have been the end of it.
Supporters of the above proposals estimate the cost of the projects to each homeowner to be $20,000 and $40,000, respectively. One can safely assume that the actual cost will be two or three times that. (I live in the Big Dig state.) So my decision to ignore the election could end up costing me quite a bit.
