Amid the national campaign frenzy over voter fraud and election security, Oregon’s secretary of state remains busy assuaging any uncertainty over the process.

In Oregon, three vendors supply the machines that count ballots, according to the Secretary of State’s Office, who oversees the state’s elections. None of those machines, called tabulators, are connected to the internet.

The three companies providing tabulator machines in Oregon are Hart Intercivic, Inc., Election Systems and Software (ES & S), and Clear Ballot, according to the secretary of state’s office.

A spokeswoman for the Secretary of State’s Office said she was “limited” in providing any further information about the machines due to “security protocol.”

Clear Ballot’s voting system, ClearVote, will be used in nine Oregon counties, processing about 57 percent of the state’s votes, according to a Nov. 1 news release from Clear Ballot.

Each of Oregon’s 36 counties performs a post-election audit of the tabulating machines, according to the Secretary of State’s Office.

County clerks will recount — by hand — three elections: one randomly selected ballot measure, the race where the top two candidates received the greatest total number of votes in the county, and a randomly selected statewide race.

If the results don’t match up, the next step, under Oregon law, depends on the difference between the tabulators’ result and the hand count.

Under a certain threshold, the vote tally’s count is the official count; above that threshold, the hand count is done again, at which point either the vote tally system is the official count or the hand count is redone for all races, depending on the difference between the tabulators’ result and the second hand count.
