I love how the same people who take every Democratic-friendly poll and even Democratic internals at face value always rush to remind us that (R)emington is basically just cooking up R-friendly numbers and shouldn’t be trusted, even though their final poll in 2016 actually underestimated Greitens and Trump significantly. But sure, go ahead and underestimate McCaskill's (or Heitkamp's, Tester's, and Donnelly's) vulnerability to your heart's content, I’m sure it’s just Republicans being overconfident again.
PPP poll, commissioned for a D-PAC: "Looks alright to me."
Remington poll: "Well this is obviously a Republican poll so we can't trust it."
Seriously.
