So much for SurveyMonkey's Trump+6% in Nebraska.
Not saying that isn't probably way off, but considering the very unusual circumstances of this Senate race (relatively/performatively anti-Trump senator will likely get some crossover vote, especially against a Democrat tainted by scandal who has lost the support of his state party in favor of a write-in candidate), I wouldn't draw many conclusions about the presidential numbers based on this.
2014 was of course an eternity ago politically speaking, and was a low-turnout, Republican midterm wave year, but Sasse got 64% that year and won every county in the state. Even with Janicek's problems, I doubt he is going to be able to replicate that kind of performance. Nevertheless, this race is far and away Safe R, and I expect Sasse to outperform Trump by a decent amount.
