Really didn't think Kander had a chance, but his ad showing the whole Blunt family as DC Lobbyists with Roy running point to get legislation passed has been damaging.

MISSOURI — “lean Republican” to “toss-up”
This is the most surprising toss-up on our map. Sen. Roy Blunt (R-Mo.) wasn't considered a top Democratic target to start the cycle, but he has struggled to put away Democrat Jason Kander, even though he comes from a state that Donald Trump is expected to win.
Basically every poll except the most recent one from automated pollster Emerson College shows Blunt ahead — that poll put Kander up by two points — but that poll and strategists all see this race as being highly competitive.
Kander is doing what he needs to to be competitive in a state that is trending red at the federal level: He's keeping pace with Blunt on money, and he recently got national buzz for what many politicos say is hands-down the best campaign ad of the 2016 cycle.
