There is a main problema about this idea, to implementar It you need that all People have accesos to Internet, and that's something hard to implement. And those without access to Internet will not be able to vote.
So, from my point of view the idea is good but the implementación is complex.
It becomes complex because privacy is being invaded for which every government is giving importance. Thus, there will be some hindrances about red tape and bureaucracy about it. There will be officials/politicians that will be subject against it because they've got some ploy or there will be plans that can't be executed when there's transparency with the votes and can be seen real-time through blockchain. It's a good technology to be adopted if the whole sector of the government agrees to make a plan and law for this. I am optimistic about it upon understanding the basics of blockchain and how it works but realizing that a government will always work as a government, looks like this is going to take time until forever to be tested by most. So, from my point of view the idea is good but the implementación is complex.
