So what really happens if Donald Trump refuses to concede the election if he loses to Hillary Clinton? Probably nothing legally, election experts say. Though considered an essential act to foster a peaceful post-election political transition of power, concessions by losing candidates are a formality – not a legal requirement. “Just saying the words ‘I concede’ have no legal effect,” said Richard Hasen, founding co-editor of the Election Journal and author of the Election Law Blog. “What would have a legal effect is if he filed for a recount or do some sort of election contest. In short, we don’t have a constitutional crisis on our hands if we don’t have a gracious concession on election night, even if the result appears a blowout,” Edward “Ned” Foley, author of “Ballot Battles: The History of Disputed Elections in the United States,” wrote on his blog last Friday.
