My country just had its general election and it was marred by electoral malpractices. Some of the data on the national electoral body's website was manipulated and this led to the rigging of the elections. The blockchian could help in conducting a free and fair election because data that is recorded in it can hardly be tampered and is also immutable.
In my opinion, the application of the blockchain system in data collection on election results is very consistent with the aim of elections in every country to produce clean, honest and fair results. The country I live in is currently in the process of collecting data on election results which were just finished a few days ago and are currently still collecting data on vote results in each region. The problem lies in the results that use a data collection system that is very far from the actual data collection system or the administration's data collection system which can easily be changed by other parties.
If blockchain is applied to collect data on election results, I am 1000% sure the results will be in accordance with reality. There is no data manipulation or it is far from criminal to manipulate data in the recap.
