Biden then won 18 of the next 26 contests. With the suspension of Sanders's campaign on April 8, 2020, Biden became the Democratic Party's presumptive nominee for the presidential election. In June 2020, Biden met the 1,991-delegate threshold needed to secure the party's nomination. Joseph Robinette Biden Jr. was born on November 20, 1942, at St. Mary's Hospital in Scranton, Pennsylvania, to Catherine Eugenia "Jean" Biden ("née" Finnegan) and Joseph Robinette Biden Sr. The first of four siblings in a Catholic family, he had a sister and two brothers. Jean was of Irish descent, with roots variously attributed to County Louth and County Londonderry. Joseph Sr.'s parents, Mary Elizabeth ("née" Robinette) and Joseph H. Biden, an oil businessman from Baltimore, Maryland, were of English, French, and Irish descent. Biden's paternal third great-grandfather, William Biden, was born in Sussex, England, and immigrated to the United States. His maternal great-grandfather, Edward Francis Blewitt, the child of Irish emigrants from Rappagh, Ballina, County Mayo, was a member of the Pennsylvania State Senate. Biden's father was wealthy but had suffered several financial setbacks by the time his son was born. For several years, the family had to live with Biden's maternal grandparents, the Finnegans. When the Scranton area fell into economic decline during the 1950s, Biden's father could not find sustained work. In 1953, the Bidens moved into an apartment in Claymont, Delaware, where they lived for several years before again moving to a house in Wilmington, Delaware. Joe Biden Sr. later became a successful used car salesman, maintaining the family's middle-class lifestyle. Biden attended the Archmere Academy in Claymont, where he was a standout halfback and wide receiver on the high school football team; he helped lead a perennially losing team to an undefeated season in his senior year. He played on the baseball team as well. Academically, he was a poor student but was considered a natural leader among the students and elected class president during his junior and senior years. He graduated in 1961. He earned his bachelor's degree in 1965 from the University of Delaware, with a double major in history and political science. He played halfback for the Blue Hens freshman football team. In 1964, he met and eventually married Neilia Hunter. He played varsity football as a defensive back.
