What is Old, and New, and Scary in Russia’s Probable DNC Hack

What is Old, and New, and Scary in Russia’s Probable DNC Hack - Lawfare:
"...There is nothing new in one nation’s intelligence services using stealthy techniques to influence an election in another.
...The data breaches are raising questions as the U.S. considers whether to move toward electronic balloting. 
More people than ever are using the internet to register to vote and to request mail-in ballots.
Some states have even become vote-by-mail only in recent years.
“If you can’t keep the voter registration records safe, what makes you think you can keep the votes safe?” asked Pamela Smith, president of election watchdog Verified Voting.
For a politically inclined hacker, insecure voter data could “very easily” create a pathway to “massive” voter fraud, said Joseph Kiniry, CEO of Free & Fair, which advocates for secure digital election systems.
“If you can go in there and delete rows based on someone’s name or political affiliation, we will have a massively screwed up election process on the day,” he said.
The Russian hack of the DNC was small beans compared to the destruction of the integrity of a national election result.  
This scary thought raises an OPM-hack-inspired question:
Who in the U.S. government is responsible for this problem?  
Election fraud is typically the responsibility of election officials working with law enforcement officials.
But when election fraud with national consequences is potentially threatened by foreign adversaries, it should become the responsibility of (at a minimum) national intelligence officials.
But are they on this problem? 
Does the United States government have a well-worked out plan to ensure that our highly computerized and highly decentralized system for electing the President is protected from foreign disruption via cyber-exploitation or cyber-attack?  
I have no idea—but I seriously doubt it."
