Yeah, flawed exit polls + Democratic media bias. They also called NH for Clinton at poll closing time, and it was very close as well. Not to mention that they projected Democrat Wyche Fowler as the winner in the GA Senate race (Fowler later lost to Republican Paul Coverdell in the runoff).
The Georgia senate race was too close to call.
Georgia has a law that requires the winner of a GE race (including Presidential electors) to achieve 50% to avoid a runoff. Georgia was projected for Clinton early, but taken off the board later on after reporters learned that there was a runoff (Fowler was close to 50%, but Clinton won Georgia with 43% as Bush refused a runoff.)
Georgia has never had any such law applying to presidential elections.
Fun fact: when Georgia originally adopted its runoff law, it actually did apply to Presidential elections! This remained the case until the law was changed in March of 1968 to exempt them from the runoff requirement (otherwise a runoff would have been required after that year's election. This wasn't a coincidence - Wallace supporters in the General Assembly were expecting a win and didn't want a runoff to jeopardize it)
