The error with 2000 General Election data on JoinCalifornia (non-final vote counts were included for some races) has now been corrected.
The results in which the error was found included the Presidential, Senate, Congress, State Senate and Assembly (but only in low-district numbers in the far north part of the state).
This error did not result in any incorrect election outcomes, just vote totals for candidates that were usually 100-500 votes less than the actual final count.
Thank you for your patience.
