This year's presidential race is one record-breaking election, from the total number of vote turnouts to the process of electing a new president.

Former vice president Joe Biden has been elected as the 46th president of the United States on Saturday. It was after he won in swing states, including Pennsylvania, Nevada, and Arizona.

Joe's running mate Kamala Harris was elected as the 49th vice president of the United States, making her the first woman in the position.

With Joe's win, it made his wife, Jill Biden, the nation's new first lady. 

Jill Biden

Jill Tracy Jacobs Biden was born in Hammonton, New Jersey on June 3, 1851. Even when she was born in New Jersey, she was raised in Pennsylvania for the most part.

Jill has four siblings and has lived in Hatboro, Pennsylvania. Experts cited this part of Jill's life as a factor for helping Joe win the presidency.

Joe met Jill three years after losing his first wife, Neilia Hunter, and his one-year-old daughter in a car accident. Joe was then left to raise their sons, Beau and Hunter, alone.

Joe said that Jill gave him back his life, according to his 2007 memoir "Promises to Keep," as reported by Style Caster.

"She made me start to think my family might be whole again," Joe said in a report. At the time, Jill had just filed for divorce from her husband, Bill Stevenson, a Delaware senator.

In a 2016 interview, Jill explained that she met Joe through a blind date set up by Joe's brother, Frank, who knew Jill at the University of Delaware.

"I was a senior, and I had been dating guys in jeans and clogs and T-shirts, he came to the door and he had a sport coat and loafers, and I thought, 'God, this is never going to work, not in a million years," Jill noted in a report.

She added that Joe is nine years older than she is, but they really hit it off. Jill remembered telling her mother that she had finally met a gentleman. 

When she met Joe, Jill worked as a full-time English professor at Northern Virginia Community College in Annandale, Virginia.

Jill noted that if they get to the White House, she will continue teaching, adding that it is vital that people value teachers and their contributions.

Jill worked as a community college teacher while Joe served as vice president under the Obama administration.

In a recent CBS News report, she said that she teaches a lot of immigrants and refugees, adding that she loves their stories and who they are as people.

Jill has a bachelor's degree, two master's degree, and a doctorate in education from the University of Delaware.

Joe gave up his presidential run in 2016 due to his son's death, Beau. He then decided to run for the third time this year. 

Jill spoke of how their personal rules will help her and her husband in their new public roles. She noted that you make a nation whole the same as making a broken family whole, with understanding, love, and small acts of kindness, according to an ABC report.
