Likely R.
2018 was a wave year and even then Kelly only narrowly edged out Kobach (plus Orman skewed the results a bit)
Bollier is a strong candidate for the State and could surprise us, but I am skeptical.
I wouldn't say Kelly's 5-point win was narrow...plus as you said Orman skewed the results; she would have easily garnered a majority and won by even more without Orman siphoning away nearly 7% of the vote. Kobach's 43% statewide showing was utterly abyssal for a Republican running anywhere in the Great Plains
