Bush v. Gore (2000)
The Supreme Court halted Florida's presidential recount in a 5-4 decision. The ruling effectively handed the presidency to George W. Bush by about 537 votes. It turned on how and when ballots could be counted under state and federal law.
Al Gore conceded within a day, and Bush became president.
The case became the benchmark for the Supreme Court resolving disputes over ballot-counting mechanics with national stakes.
Like Watson, it shows the Court deciding the technical rules of which ballots count, with control of government hanging on the answer.
