1. Blockchain technology could be theoretically used to secure elections. Some example usage: When people register to vote, assist them with setting a key pair and allow them to enter their public key with their registration. They could then verify how their vote was counted after the election. Not sure if it would be superior to paper voting still as it could then be used to buy votes, but maybe there are some narrow applications, or a multi-sig approach where someone could know, but not prove it is their vote without the help of a third party. It is still better than current electronic-voting in this scenario. As a side note, there is definitely a use for public key registration associated with government identification as it would solve ID theft for good. 2. It could also be used for public records and secure/lower cost for chain of custody applications.
