Honestly, seeing as there are seemigly no limits to the lengths that Kris Kobach will go to to ensure that Roberts wins, I'm starting to question whether it is even possible to have a fair election in Kansas at this point. If there's any way for Kobach to somehow steal this election for Roberts, I tend to think that he will do it. The man appears to have zero morals.
But the thing I don't understand is, what does Kobach get out of this deal? It's one thing to stand by Roberts, but at this point Kobach is expending a substantial amount of his own good will and political capital on highly transparent partisan shenanigans designed to prop up a relatively unpopular incumbent. What's the upside for Kobach? This can't possibly help him in his own race. Threatening to delay military ballots? That attack ad practically writes itself.
The upside is that he'll be able to call in favors once he inevitably runs for Governor. If Brownback/Roberts are defeated, he'll probably end up going down as well. Even if he managed to scrape by, it wouldn't bode well for his political future.
