Hey Sorry for the late reply.

In January this year there was a poll that had Fischer ahead by 17. But I'm not sure how reputable that polling organization was. That one is listed on 538 Here

I was actually wrong misremembering the June poll, it was done by a Republican organization. It did have Fischer (R) with a massive lead. 63-28. But this was June, and doesn't seem to be the best poll. I got it from a politico article here

Either way I'm so surprised that no organization has decided to do any real polling in the state. Who knows, maybe its more competitive then people are assuming.
