Minor correction/clarification: the Supreme Court ruled 7-2 that what was going on in Florida violated the Constitution's election protections. The 5-4 decision was more contentious since it stopped any further recounts.
Since the subsequent unofficial recounts almost all gave the state to Bush, and all the official recounts that Gore asked for would have given the state to Bush, it's kinda funny people still whine about this decision.
There are more than one possible view. My view is that the US Supreme Court did not decide the election. The US Supreme Court put down the attempted coup, of the legally elected current administration, by the Supreme Court of Florida (SCOFLA). The US Supreme Court did this by upholding the validly completed ballots of correctly registered voters as certified by the State of Florida.
I support that decision of the United States Supreme Court. George W. Bush is, lawfully and Constitutionally, the President of the United States of America and Commander in Chief of our armed forces. I also support the decision of the United States Supreme Court of June 26, 2003, that John Geddes Lawrence and Tyron Garner have the right to privacy in their own home, and therefore that Steven Malcolm Anderson has the right to privacy in his own home, and therefore that you have the right to privacy in your own home. I oppose those who are and have been trying to subvert the United States Supreme Court.
