There is a wide range of blockchain application but electronic voting by having blockchain system is something unusual yet very innovative. I've read some articles related to this one and it is really interesting the votes serves as the open ledger to garner a more transparent election that cannot be altered by any external means so it is very safe and fair election to be done. Country such as Japan and Switzerland never fail to impress me in terms of technological advances they are showing to the world, hope this would be another thing in the future for electronic voting in all world's country.
