The votes gave Democrat O’Connor another 190 votes to narrow Republican Balderson’s lead.
What am I missing here? Seems to me like if they found 500 votes and 190 went to the Democrat, wouldn't the remainder (310) go to the Republican. Or maybe there were other candidates in the race? Even if that's the case, how many of the 500 votes went to the Republican?
Read post 11, it has the answers you seek.
The author of the posted article did not express this clearly. What he means is that the Democrat had a MARGIN of 190 votes among the ballots that were purportedly "found" and not counted when they should have been. From other sources, the number of "found" ballots was 588 -NOT 500. So, not counting any votes for other candidates (you could assume there would be at most a handful of such votes, anyhow) that would mean that O'Connor would have gotten 389 and Balderson 199 of the "found" votes. That figures out to 66% for the Democrat.
Now this wouldn't sound legit if the area covered by the "found" ballots was demographically similar to the entire CD, which voted close to 50-50. So if there was no particular demographic factor which distinguished the geographic area from which these votes purportedly came (e.g., more heavily black or Hispanic), you would have to conclude that the "found" ballots were a total fake manufactured for the purpose of cheating.
