"I felt like a million bucks," Schultz, 98, told ABC News from her home in Rockville, Maryland, where she plans to watch election returns on Nov. 8.
Schultz, whose first presidential vote was cast for Franklin Delano Roosevelt, said she "never did" think she would vote for a woman for president.
Schultz's granddaughter, Sarah Bunin Benor, of Los Angeles, said she believes the potential of seeing Clinton as president is keeping Schultz alive.
"She was in the hospital about one-and-a-half years ago and was diagnosed with a heart condition and was told she only had six months to live," Benor said. "She kept saying, 'I want to live long enough to vote,' and now she wants to see [Clinton] get inaugurated so it's almost like she's living for this election."
Schultz asked her granddaughter to share a photo of her voting for Clinton by absentee ballot on Facebook earlier this month. The post received 2,000 likes and sparked an idea in the minds of Benor and her mother, Roberta Benor, who is Schultz's daughter.
The website has a submission page for women, or their family or caregivers, to submit a photo and a quote on what it was like to vote for Clinton for president.
"We wanted to have it in the first person, in their own words, partly because often people think of really old people as not having much agency, of being disabled," Benor said. "We wanted to highlight that many of them are still thinking strongly about these things."
The website so far has nearly 20 submissions from women across the country ranging in age from 96 to 105-years-old.
A photo of Stellajoe Staebler, 100, of Centralia, Washington, was submitted by one of her three daughters. Staebler was born in 1916 and remarked, "I am grateful that at the age of 100 I'm still able to vote and that there is a highly qualified woman to vote for."
"She thought about that and how she was proud to be able to vote for a woman," Staebler's daughter, Jo Ann Staebler, told ABC News. "She was also proud to have voted for the first person of color."
Jo Ann Staebler said her mom, who never went to college but was a longtime community advocate for environmental, immigration and peace issues, keeps up with the election and believes Clinton is the better candidate.
Garvin Colburn, 96, of Chattanooga, Tennessee, said she submitted her ballot for Clinton because she also believes Clinton is the best candidate.
"She votes for the best person, whichever candidate that is," Colburn's daughter, Cecilia Coburn, told ABC News. "She's 96 and wanted to be sure that she went to vote."
Colburn was born the year women gained the right to vote and has not missed an election in which she was eligible to vote.
"She had a wonderful time," Colburn said of her mom's voting experience this year.
"I can't believe we just put the biggest crack in that glass ceiling yet," Clinton said to supporters when she secured the Democratic nomination in July.
Estelle Liebow Schultz, whose decision to tell her voting story on Facebook sparked dozens of others to speak out too, said she thinks it is "terrific."
"I think many more women should be heard from," Schultz said.
