The large number of Dem governors likely protects us in this scenario, but imagine a state like PA instead deciding to split the electors based on the vote. Or a state as gerrymandered as WI allocating most of it's electors by congressional district. It would end up having the same effect. GOP playing and changing the game to flip the election in their favor. The problem is that our system has these problems inherent in our system. And changing the system requires getting the vote of those who the system is biased towards.
The only way to protect ourselves against this is a national popular vote.
Wouldn't states splitting the electors do almost the same as a national popular vote? It's not accurate but the 40% of D Texans and the 30% of R Californians would be represented.
No, a national popular vote would be mandating that the game be changed across all states at the same time.
I'm talking about individual states trying to make plays based on polling a few weeks out from an election. Let's say that a likely scenario based on polls is:
Trump takes FL, OH, NC, and one of [AZ, WI, MI]
Biden take the other 2 and PA
PA could say they're going to actually split their votes effectively throwing the entire race to Trump. It would be entirely constitutional, democratic, but highly unethical.
The problem is a single state being able to change its rules at a moment's notice in order to swing electoral votes a particular way.
