A database is a central point of failure. Nothing stopping a sysadmin or a hacker able to get shell access from just deleting a bunch of votes, or taking the whole system offline.

Also, in a blockchain system, any person can connect a node to the network and can see all of the votes that are occurring/have occurred, and can somewhat verify the results of the election.
