“Elections are part of America's critical infrastructure. They must go on, as they have in our history during civil war, crushing recessions and deadly epidemics,” Raffensperger said.
It would take legislative action or an executive order from Gov. Brian Kemp to move the election, Raffensperger said. Election dates are set in law to protect the rights of overseas voters who need time to receive and return their ballots, he said.
Under state law, the secretary of state can postpone an election for 45 days during an emergency, as Raffensperger did March 14.
Raffensperger believes the law only allowed him to delay the election until early voting resumes April 27, a period of 44 days.
House Speaker David Ralston, a Republican from Blue Ridge who wants to postpone the election, has said he believes Raffensperger can delay the election again when "an emergency is ongoing."
Ralston said Raffensperger already exercised power to exceed the 45-day limit because the gap between the original March 24 election and the new May 19 date is 56 days.
A change in state law is unlikely because the Georgia General Assembly is suspended during the coronavirus pandemic.
The letter from Georgia's congressional delegation was signed by U.S. Sens. David Perdue and Kelly Loeffler, as well as U.S. Reps. Buddy Carter, Drew Ferguson, Rob Woodall, Austin Scott, Doug Collins, Jody Hice, Barry Loudermilk, Rick Allen and Tom Graves.
