IN-Gravis: Sen. Donnelly (D) +4

[Progressive Pessimist]

It is pretty clear at this point that Donnelly is in a better position than either Heitkamp or McCaskill. He also seems to be doing better than Tester. This poll is in line with previous polls.

Even if this poll isn't evidence of that, that's how this race looks to me as well...minus the Tester part.  I used to think Donnelly was the most vulnerable Trump state Senator, but lo and behold: Heitkamp, McCaskill, and Nelson might just lose before he does. I would still consider it a tossup though.
