Kind of dumb for the NRSC to release this, but okay. I guess it's just to counter the "Titanium Tester" narrative? Becuase this poll actually makes me feel better about his chances than I did before I saw it.
Most people didn’t expect this race to be close at all in a D wave year with Rosendale as the Republican candidate. This isn’t the only poll showing a close race, CBS/YouGov had Tester up by 2, and I’m pretty sure they’re not a R pollster. Tester is still favored obviously, but I don’t see why the NRSC is "dumb" for releasing this?
So then yes, it was just to counter the narrative that Tester was heavily favored? Because if you viewed it as a toss up beforehand (as I did), this just gives you more reason to think Tester is legitimately up by at least a few points.
