New Jersey’s 14 electoral votes have gone to Democrats in every presidential election since 1988.
Joe Biden has won Delaware’s Democratic presidential primary, while President Donald Trump has won the state’s Republican presidential primary.
Biden, a longtime senator from Delaware before serving two terms as vice president, is already the party’s presumptive nominee. He has accumulated enough delegates to win the nomination at Democrats’ convention next month.
Republicans have coalesced around Trump, who is seeking his second term in office. Republicans are also holding their presidential nominating convention next month.
