You're the fool if you think this is as significant as you and other Libs are making it out to be.
I see Moore's loss an anomaly along the line of Todd Akin's loss in 2012. Ironically, that's one of the 8 seats expected to flip back to the GOP in 2018.
These are the Democrat seats up in 2018 in states that Trump won:
FL: Bill Nelson (T +1, Rubio(R) +8)
IN: Donnely (T +19, Young(R)+10)
MO: McCaskill (T +19, Blunt(R) +3)
MT: Tester (T +21)
ND: Heitcamp (T +36, Hoeven +62)
OH: Brown (T +8, Portman +21)
WV: Manchin (71 in 2017, Trump won state +42)
WI: Baldwin (T +1, Johnson(R) +3)
MO and WI are clearly within the margin of error, but I don't see Democrats winning the other six.
