There were 13 ballot challenges made and two of them will likely change. However, of these two, one belonged to Goldner and one belonged to Schmidt so there will be no net effect from those. There is one additional vote that could potentially go for Schmidt because the machine read it as a no-vote. All other challenges are not likely to stick and even if they did there will not be enough votes for Schmidt to overtake Goldner.
It will soon be official - Karen Goldner will be the next 2nd District councilmember. Congrats to Karen (again)!
