Based on the above discussion, the Sec/State of Colorado has no say in how the electors vote, and was wrong to interfere. The interference was illegal unless Colorado law allows it (not discussed).
I think that will be the Fort Sumter of CW2. When a liberal state turns over their voters rights to vote Trump or whoever and turns an election.
That is surely when it will happen. Whether it happens by their own citizens or invaders from neighboring states to find the traitors. So be it.
On the drive home from work, I’ve re-considered my position...
According the the Constitution, the FedGov should have no say in how the States apportion their electors.
If Colorado law allows their SecState to fiddle with electors, then OK. If not, then the SecState is in violation of STATE laws.
