A number of states are blocking web traffic from foreign countries to their voter registration websites, making the process harder for some U.S. citizens who live overseas to vote, despite the practice providing no real security benefits.
On its face, the "geo-targeting" of foreign countries may seem like a solid plan: election officials around the country are concerned about foreign interference after Russia's efforts leading up to the 2016 election, so blocking traffic to election websites from outside the United States might seem like an obvious defense starting point.
