A recent report by TIME magazine has brought to light the extent the federal government went to restore faith in the United States' democratic process and protect U.S. voters after hacks that began in Riverside County, Calif.

Shortly before and after the June 7 California presidential primary, dozens of people complained about their voter registration being tampered with — their party affiliation had been changed unbeknownst to them.

Riverside County District Attorney Mike Hestrin opened up a preliminary investigation into the matter, but the California Secretary of State’s system did not keep track of IP addresses, which led to the hunt for the culprits to turn "cold."

Add that to the finger-pointing by California Republicans and Democrats, it was easy to overlook the gravity of the situation.

The piece by TIME magazine seeks to put the speculation to rest. The magazine points to Russia as the likely source of a hack on the county's voter information last year and includes a 15-page cybersecurity response plan by the Obama Administration.

This plan revealed just how concerned Washington was about the hacking issue. Officials had wondered if the hacking in California was just a test run by the Russians, getting them prepared for Election Day, with the ultimate goals of causing confusion and undermining trust in the democratic process.

The feds' plan also discussed the possibility of sending "armed federal law enforcement agents" to polls and the use of "Active and Reserve military forces" in a worst-case scenario, among other things.
