Well, not a regular blockchain: you don’t want individual votes to be public and easily linked to the person making the vote.

Blockchains are possibly the worst way to implement voting at least in a “public” / governmental setting. You need to be able to do zero-knowledge votes, meaning that you want it to be impossible to look at a “vote transaction” and say who did the voting and who they voted for, but also know with (practically) absolute certainty that the vote was done by a valid voter and isn’t a duplicate, and then finally you want to be able to tally the votes per candidate even though you can’t look at an individual vote and say who it was for. So any sort of “classic” blockchain is almost the literal opposite of all that, with public transactions that are tied to public identities and where everyone can tell what happened. What you need is something that either allows or is based on zero knowledge proofs, but I honestly dunno if any current project can do this out of the box, haven’t kept up to date that much lately
