Too many secretaries of state see themselves as governors in waiting, but Mr. Raffensperger was enthusiastic about fixing the nuts and bolts of the election machinery. In just two years in office, he has improved Georgia’s election security in several ways.

First, he replaced outdated, paperless voting systems with accessible, paper-based voting systems, which allowed for audits of elections in Georgia. For this election, given the closeness of the vote, Mr. Raffensperger is planning a hand recount, but going forward, Georgia will establish risk-limiting audits, which use statistical sampling to confirm results.

He also joined the Electronic Registration Information Center, which will enable Georgia to keep its voter lists more up-to-date, removing people who have died or moved out of the state. And he further cleaned up the Georgia voter rolls by establishing an automated verification and registration system to make elections more efficient and reduce the opportunity for voter fraud.

After the presidential primary, which featured long lines and wait times at polling places, Mr. Raffensperger worked with local election officials to streamline the voting process.
