McCaskill is certainly putting up a far better fight than I originally expected. At the end of the day it is tough to see the votes coming together for any Democratic Senate Candidate to reach 50% in a lockstep R+22 state, but if there is a way to do it, McCaskill appears poised to find it.
Where the hell did you get the R+22 from??? Plus, you don't need 50% to win.
Hillary +3 Nationally ---> Trump +19 in Missouri
Typically "R+X" is used in reference to Cook's PVI scores, which for Missouri would be R+9.
If Dems could win PA-18 which was R+13 we can definitely win MO with an incumbent.
