It's an interesting idea, and I applaud your efforts to improve election integrity... but it sounds like it doesn't verify that the data being added to the blockchain is legit... IOW, garbage in garbage out? Data from electronic voting machines is very sus... and is proven to be easily manipulated if you have the master key. Anyway, kudos for your efforts and I hope you can help push election integrity in the right direction.
Immutable Public Records that anyone can verify is a net benefit. This is not the silver bullet (because there are none) but it does help anyone seeking truth.
