I live in Jean Schmidt's district. It has been Republican for a long time. I think she will win. Wulsin is a RAT/lib/socialist poseur.
Predictions on the upcoming election are not at all uniform, in any case. The New York Times pre-election map says Schmidt's seat is "safe Republican." That seems to contradict this poll. I suspect anyway that Schmidt will win. Not only is this a strongly GOP district as you say, but it is very rare for an incumbent who won a special election to be ousted when they seek a full term.
