My current predictions for races which will be competitive, which are highly subject to change:
TN: Bredesen +1 (D gain)
IN: Donnelly +2
MO: McCaskill +4
ND: Heitkamp +5
FL: Nelson +5
NV: Rosen +5 (D gain)
AZ: Sinema +6 (D gain)
WV: Manchin +6
TX: Cruz +7
MT: Tester +9
And for the races which are on the cusp of being competitive, but aren't really:
NE: Fischer +9
OH: Brown +10
WI: Baldwin +11
MI: Stabenow +13
PA: Casey +15
Eh, I take pride in being a 24/7 around the clock Brown fanboy but I highly doubt he can win by that much. Maybe 5 or 6 but Renacci is a pretty typical Republican, I doubt he'll lose in a landslide.
