There has to be some way for campaigning politicians to make non-watertight promises too. (For almost any promise you might make, there will be some circumstances in which breaking it would be the right thing.) Given the option of making truly watertight promises and making ones with escape clauses, most politicians most of the time will make the ones that they can get out of. So then who will make the most impressive-sounding "watertight" promises? Candidates who know they'll never actually get into power. Candidates who expect to be able to weasel out of those allegedly watertight promises somehow. (They probably will.) This doesn't sound to me like an improvement. Am I being too cynical? Is there some way to have watertight campaign promises without these problems?
