Joe Biden delivered a hopeful message from Wilmington, Del., on Wednesday afternoon, as no winner in the U.S. election has been declared as mail-in ballots were still being counted. Biden made it clear that if he is elected, he will serve all Americans and not just his supporters. He said his team is confident he could win the race for the White House, though was careful not to prematurely declare a victory. The lack of a clear result means Americans — and the world — may not know who the next president is for days at best. At worst, legal challenges could drag the contest out for weeks, an echo of the 2000 election that was ultimately decided by the Supreme Court.
