I think the final numbers will be very close to this, Marshall wins by 5-8%.
Why exactly has this race pulled away from the Democrats in recent weeks? I'm aware of some of Bollier's recent missteps, but are there any factors that you think have come into play here?
Not the person you quoted, but I'd assume a lot of it is just partisanship kicking in. Kansas hasn't elected a Democratic Senator since 1932, after all, and state races are different from federal races. My guess is Kobach would still have won at this point.
