I will throw what is likely an unpopular opinion. I think what you are doing is responsible. If you don’t actually feel like any candidate is any worse than the others, in any way, in even the least way ; then I think you are doing the right thing. If you vote randomly, with no basis at all, doing eannny, meanny, minne, moe or such. Its way better to not vote. Now if you think any candidate is even the slightest bit worse for your country than the others ; then you should vote. I have much more respect for you deciding you have no basis to cast a ballot and choosing not to do so than some folks in my country who seeing and acknowledging a greater evil choose to not vote to punish the lesser evil for not being good enough. Your take as I read it is sensible.
