There is a second thread for this? Weird.
Looking at the Election Results on this website:
Definitely looks like this wouldn'tve helped Obama or John Gregg. Donnelly beat Moreduck by almost 150,000 votes so it wouldn't even benefit the Republicans. Congressional Results seem to verify no adverse outcome either:

So yes, in this case as the article says that the votes didn't seem to have that much of an effect on the race. However, it should still be alarming that votes would go undiscovered for this long. I mean, what if somebody finds those missing Nixon votes in Aurora? Our timeline could be in jeopardy!
Anyway, that's my two cents. All the races that happened in that district were pretty well decided, regardless of how the 3,700 people voted. Even if 100% of them voted one way or the other it wouldn't affect the election. Romney would still win Indiana, the nameless GOP congressman would've still gotten re-elected, Joe Donnelly would still wipe the floor with Moreduck, the results wouldn'tve stopped the overwhelming GOPslide in the state legislature, Mike Pence would still become Governor, and Greg Zoeller would still be Attorney General.
With that said, imagine if these 3700 votes were missing from Columbus County, North Carolina.. . . . . . . . .
