Galloway is a good candidate, but it's hard to see her beating a noncontroversial generic R like Parson in blood red MO at the same time Trump is landsliding in the state.
Not to mention she barely cracked 50% against one of the worst candidates that was a literal fraud and had literally no money despite it being a D+9 Democratic wave year. Still impressive by Missouri Democrat standards no doubt, but I don't see how she wins unless Parson becomes super unpopular and/or scandaled. The real question is the margin.
All this is true and I have thought over it a lot but to Galloway's credit and defense:
1) The Senate race very much over shadowed the Auditors race. Sort of a shame as it is elected in midterms in theory to be a check on the executive branch. But few people knew anything of Saundra McDowell or who she was. They just saw the (R) next to her name.
2) 2018 was a D+9 year yes but we did have somewhat of a counter wave and we can not always expect that in future elections.
3) Now instead of being appointed to an office by an unpopular governor that was held by a Republican who died by suicide, Galloway now won re-election in her own right and that does bring some good will.
4) Galloway never had a contested office until last year.. and in a stand alone race she would have likely won by a larger margin.
so overall I think she will only lose by a few points next year but at least we know Parson likely won't landslide now!
