I've read some arguments that since Bush's lead is large enough that most errors wouldn't have changed the outcome, we should not even bother looking for errors. I find this illogical. First, we do not know the magnitude of any potential errors at this point; no major discrepancies have been proven to have occurred, but there also hasn't been much time to look for them. Second, even if correcting errors in this election would not change the outcome, it's still important to discover and correct the underlying causes so future elections will be more accurate.
