After an election this week in which Georgia
Then she learned that under a quirk in Georgia law she won't be allowed.
The state constitution stipulates that only those who registered to vote in the general election are entitled to vote in a run-off election, meaning that anybody who wasn't registered by March 20 is ineligible to vote in the election.
"It's so frustrating," said Kilgore, a 57-year old substitute teacher.
She had recently moved to the district and was not able to vote in Tuesday's election due to a misunderstanding when she updated her driver's license. But she assumed she would have plenty of time to register before June 20.
"Why do the same rules not apply to the runoff as to any other election?" she said. "Why are they trying to make it harder for people to vote?"
On Thursday, the Lawyers' Committee for Civil Rights Under Law, a Washington-based advocacy group, filed a complaint in federal court in Atlanta, claiming Georgia's law violates the 1993 National Voter Registration Act, which prohibits states from imposing a registration deadline of more than 30 days before any federal election.
"Cutting off the registration period makes absolutely no sense," said Ezra Rosenberg, co-director of the committee's Voting Rights Project. "We should be doing everything to help people vote. Not putting arbitrary blocks in front of them, particularly blocks that are in violation of federal statutes. It's just wrong."
At least 100 people have already learned that they will not be allowed to vote in the June election because of the law, and thousands more could be in the same situation as they try to register, Rosenberg said.
David Dove, chief of staff for the Georgia Secretary of State's office, issued a statement dismissing the lawsuit as "political theatre."
"Setting voter qualifications is completely within the purview of states and the U.S. Constitution and cannot be altered by" the National Voter Registration Act, it said.
But Daniel Tokaji, a professor of constitutional law at The Ohio State University, said the Georgia law was a clear violation of longstanding federal voting rights law.
"I don't think that Georgia has much of a legal leg to stand on," he said. "Georgia has an obligation to follow federal law, period," he said.
The stakes are particularly high in this election, which will fill a seat vacated when Tom Price was confirmed as the secretary of Health and Human Services. The race is widely seen as an early referendum on President Trump.
Ossoff, a 30-year-old documentary filmmaker and former Congressional aide making his first run for public office in a traditionally Republican district of suburban Atlanta, finished in first place Tuesday with 48.1% of the vote, shy of the 50% he needed to win the seat outright.
He will face the leading Republican, Karen Handel, a former Georgia secretary of state, in the run-off.
"In this very critical election that has national implications, all voices should be heard," said Francys Johnson, an attorney who is president of the Georgia NAACP, one of the civil rights groups that is a plaintiff in the case. "That's what this is about — whether we will be expansive in our view of who can make decisions in search of a common good or hold to traditional notions that this right should only be exercised by a few."
Civil rights groups have long accused Georgia officials of gerrymandering districts and restricting voting rights. In 2005, Georgia was one of the first states in the nation to pass a strict law requiring voters to show government-issued photo identification at the polls.
