Bold prediction: Still Tester.
Yeah I feel like WV could be prone to a last minute surge of R support that MT might be a little more immune to
Yeah, that's exactly what I was thinking.
Montana is likely to be close, but Tester has the advantage. On one hand, Manchin currently leads by more than Tester. On the other hand, the bottom could fall out from Manchin at any second and cause him to collapse like a house of cards just like what happened with Heitkamp. I'd rather be in Tester's position with the far more reliable yet smaller base that nevertheless puts me narrowly ahead than have to rely on Manchin's far more volatile and uncertain (but for the moment larger) base.
