I sometimes wonder what could have been if Jason Kander had won in 2016.
If Jason Kander won in 2016, everyone in the party would be begging him to stay in the senate. Why throw away a senate seat and let a republican governor pick his replacment
This can only happen if Kander wins in 2016 and Democrats do even better in 2018 and win the senate. If we assume Kander wins and Doug Jones wins in Alabama in 2017, this means 50-50 senate. Democrats would need to win 1-2 seats in the midterms.
This means picking up seats like NV and AZ. They are going to lose Indiana and North Dakota. I suppose Bill Nelson can win Florida since it was 0.12% margin. And lets say Clair wins Missouri from Kander supportors.
Democrats now have a 52 seat majority. Kander might run since he won't cost Democrats the majority
Chris Koster could have picked his replacement. If you're butterflyeffecting a Kander victory, you might as well butterfly Koster too, he only ran two points behind.
