-In 2020, FL, IA, or NC cast the deciding electors to defeat Trump.
-In 2021, the GOP passes laws requiring those states award electors by congressional district — then gerrymanders the shit out of those districts.
Arizona casts the deciding electors to defeat Trump. The GOP repeals the state's voter-approved independent redistricting commission (or Judge Beer Bong overturns SCOTUS' decision holding it constitutional), and then same scenario plays out there.
That risk should keep us up at night.
