The key vote, which was to stop the uncontrolled vote counting authorized by the Florida State Supreme Court, was 7-2. Only Steven Breyer and David Souter dissented.
The proposed remedy, which was to allow the state of Florida to certify the votes according to existing approved counts and extent law, was 5-4. Ginsburg and Stevens joined in dissenting, but the four submitted four separate opinions as to what remedy should have been undertaken.
The media always calls this a 5-4 split decision. But the fact is that 7 of the justices agreed the Florida State Supreme Court had royally screwed up. The only real disagreement was what to do about it.
Importantly, none of the four separate dissents advocated allowing the count to proceed as they had been authorized by the Florida State Supremes!
