Isn't that almost impossible? AFAIK the votes were approximately split 3 ways across 2 republicans and 1 democrat. That's the only reason why the democratic candidate was even ahead.
In the race the Democrat was leading, the Republican candidate had a history of minor (local) scandals, and only held the seat because she was appointed to it.
