Florida 2000? If I had to take a guess.
Yep
On election night, November 7, 2000, CNN, along with the other networks, first called the state of Florida for Democrat Al Gore,
only to later retract that prediction. That projection was made at a time when polls had yet to close in the state's Panhandle, which is in the Central time zone.
In the early morning hours after election night, with the election outcomes still in doubt, CNN and the other networks called the state of Florida for Republican George W. Bush -- a projection that said Bush was the new president and resulted in wild celebrations at Bush headquarters in Austin, Texas.
The networks then retracted that call.
Based partly on the findings of the report, CNN plans to implement widespread changes in its future election night coverage.
-CNN will not use exit polls for projections in close races.
-CNN will not project a winner in a state, even if it is reported that all the outstanding ballots have been accounted for, if the balloting shows that there is less than a 1 percent margin.
-CNN will no longer project the winner in a state until all the polls are closed within that state.
-CNN will remain with VNS "if, and only if, significant changes are made to assure that the errors that plagued election night coverage in 2000 do not recur."
-CNN also will fund a sample key precinct vote reporting system in the states expected to have the closest races to ensure the network has as a second source of data to crosscheck against VNS data.
