She will do around what McCaskill did.
She will likely do worse
1. 2020 likely won’t be a D+9 year
2. Contrary to McCaskill, Galloway won’t have $40M to spend
3. Parson is a popular incumbent
4. Running on abortion is not a winning issue in MO
5. Trump will likely carry this state by +15 and will provide coattails to other conservative candidates
It is dumb to campaign solely on abortion in Missouri but even Mississippi rejected a life at conception amendment, Considering Missouri is more liberal than MS going against hardcore abortion bans can work.
