This lines pretty closely up with what we've been seeing - both candidates really struggling to break out of the mid-40's. It's been a very hard race to get a clear pulse on or for either candidate to really generate momentum in.
Basically the exact same story in KS polling in 2018 and Kelly ended up winning by a decent margin on election day. So folks writing this off are silly.
Do remember that Greg Orman was a factor in that race - his 7% was enough to make mid-40's enough to win.
Definitely silly to write off this race, but Bollier is certainly not in the same position Kelly was.
