I think the government distrust the blockchain's usage since there are still fraud in election that they are keep doing it like it was fixed. The cost is not a deal since there are funds for elections and I think the commission should make the best out of the money but I think they are just buying cheap election materials for them to keep some funds and the fixing will not be exposed. I hope some greater countries implement it so there will be no choice for some corrupt government officials to fix the election again.
