At approximately 7:50 p.m. EST on election day, 10 minutes before the polls closed in the largely Republican Florida panhandle, which is in the Central time zone, some television news networks declared that Gore had carried Florida's 25 electoral votes. They based this prediction substantially on exit polls. However, in the actual vote tally Bush began to take a wide lead early in Florida, and by 10 p.m. EST those networks had retracted that prediction and placed Florida back into the "undecided" column. At approximately 2:30 a.m., with some 85% of the votes counted in Florida and Bush leading Gore by more than 100,000 votes, the networks declared that Bush had carried Florida and therefore had been elected President. However, most of the remaining votes to be counted in Florida were located in three heavily Democratic counties - Broward, Miami-Dade, and Palm Beach - and as their votes were reported Gore began to gain on Bush. By 4:30 a.m., after all votes were counted, Gore had narrowed Bush's margin to just over 2,000 votes, and the networks retracted their predictions that Bush had won Florida and the presidency. Gore, who had privately conceded the election to Bush, withdrew his concession. The final result in Florida was slim enough to require a mandatory recount (by machine) under state law; Bush's lead had dwindled to about 300 votes by the time it was completed later that week. A count of overseas military ballots later boosted his margin to about 900 votes.
Florida Supreme CourtMost of the post-electoral controversy revolved around Gore's request for hand recounts in four counties (Broward, Miami Dade, Palm Beach, and Volusia), as provided under Florida state law. Florida Secretary of State Katherine Harris announced she would reject any revised totals from those counties if they were not turned in by November 14, the statutory deadline for amended returns. The Florida Supreme Court extended the deadline to November 26, a decision later vacated by the U.S. Supreme Court. Miami-Dade eventually halted its recount and resubmitted its original total to the state canvassing board, while Palm Beach County failed to meet the extended deadline. On November 26, the state canvassing board certified Bush the winner of Florida's electors by 537 votes. Gore formally contested the certified results, but a state court decision overruling Gore was reversed by the Florida Supreme Court, which ordered a recount of over 70,000 ballots previously rejected by machine counters. The U.S. Supreme Court quickly halted the order.
On December 12, the Supreme Court ruled in a 7–2 vote that the Florida Supreme Court's ruling requiring a statewide recount of ballots was unconstitutional, and in a 5–4 vote that the Florida recounts could not be completed before a December 12 "safe harbor" deadline, and should therefore cease and the previously certified total should hold. The Supreme Court's decision was an unsigned or "Per Curiam" ruling; the ruling was “limited to the present circumstances” and could not be cited as precedent.[47]
