Trump leads in CD2 and CD3, Cruz/Kasich tie in CD4, Cruz leads in all other CDs.
Surprising Trump is trailing in WI-07. That was slotted to be his best CD. But then the Wausau area (a major population center in the district) is heavily German, and the area quite religious, and thus perhaps "socially connected" rather than anomic, and thus more immune to Trump's siren song. And presumably St. Croix (another population node) has a Scandinavian flavor to it.
With 8 congressional districts in the state, the MoE on each individual CD is going to be huge. The CD crosstabs are fun, but I wouldn't treat them as gospel.
