Voting is not a big problem in most countries, it's not responsible for the "broken" state of politics. Meanwhile, electronic voting itself is highly controversial, as security researches point out that it introduces a huge amount of attack vectors and provide very little improvements over traditional voting.
Ask yourself, says Joseph Kiniry, CEO of Free & Fair, a company that provides secure election services, if combining the idea of an ICO and democratic elections sounds fishy or not.
At this day, every ICO sounds fishy because of their enormous failure and scam rates, so when you add some futuristic ideas that have been only theoretical for so many years, the level of suspicion only increases. And blockchain is still nearly non-existent in production, yet people hype like it's a solid technology that can be used to build anything. I personally would be more excited if instead of building utopias people first provided working proof-of-concepts on a smaller scale and then worked their way up towards bigger and harder solutions.
