Like I said in that post, this is a last resort, not a first resort.
I think the legislature has a duty to act if it is likely that the state will not be represented in the Electoral College. In think that in that case, SCOTUS would side with the legislature.

Maybe, but I'm not so sure.
I think it's implicit that the legislatures can determine the method of choosing electors consistent with their state's constitution.
The legislature of PA has already chosen that method and put it into law. According to the PA constitution if they want to change it they have to pass a bill and either have the governor sign it or get two thirds of each house to agree.
No one says they can't change it, just that they have to do it under the constitution.
I think it's very different than FL because it would unambiguously be in violation of the election laws the legislature already passed and I suspect SCOTUS would agree.
