Again, I'll say people are so polarized - and angry - that turnout is a complete guess. These models always come down to their predictions on turnout (or at least its distribution), and I don't think any past results (they usually rely heavily on what the last midterm or two looked like) will be indicative.
Yeah, with all the Kavanaugh kerfluffle, the Rs are the current leader in the "WE'RE OUTRAGED AND GOING TO THE POLLS!!!!" crowd, but there's a full month before elections. But all it takes is one incident painted a certain way (Kav gets voted through, Trump makes public ass of self again, etc.) to reverse things. So, at the least, October won't be dull, since both sides will be working to make sure they fire the last bullet before polls open.
