Democrat Jon Ossoff was the top candidate in an all-party House special election in Georgia on Tuesday night, but failed to gain more than 50% of the vote, which means a runoff election will be held in June.

As of early Wednesday morning, Ossoff had 48.6% of the vote, with about two-thirds of precincts reporting, according to The Wall Street Journal. CNN called the race just after midnight, projecting that Ossoff will miss the 50% needed to win outright, after technical problems delayed the count late in the night.
