U.S. presidential election of 2000 — Bush v. Gore A Florida judge examining a challenged vote at an operations center in Plantation, Florida, during a recount of the state's U.S. presidential election ballots, 2000.

In the 2000 Florida presidential election, a "hanging chad" refers to a small piece of paper (a chad) that was not completely detached from a punch-card ballot after a voter attempted to cast their vote.12

These hanging chads created significant problems because the automated voting machines used at the time could not accurately read or register a vote if the chad was not fully punched out. This resulted in ballots being categorized as "undervotes," where the machine recorded no vote for the presidential office.1234

During the subsequent manual recounts, election officials were forced to manually inspect these ballots to discern the voter's intent. This process introduced high levels of subjectivity and inconsistency in how different counties interpreted partially punched ballots, such as hanging or "pregnant" (dimpled but not pierced) chads. These inconsistencies in manual recounting methods and standards across Florida counties became a central issue in the legal case Bush v. Gore, ultimately leading the U.S. Supreme Court to halt the recounts.2314
