Believe what is legal? He poised a loaded question without any real substance? Adding stuff like "faithless electors" just shows the inherent bias of his question. If it is through legal pathways, that supports the opposite of being faithless, as it is based on law
It would be like me saying "do you support the governor illegally pushing through an executive order that allowed 700k fraudulent votes, despite state law makers being against it?" Adding that fraudulent part, and the faithless part just loads the question.
As you said, this is a constitutional crisis, at least in PA at this point as the state congress is bringing up their constitutional rights. So, are you opposed to state congressional/law makers using their state and/or federal constitutional rights? As this is the most pertinent question for the context of what they are trying to do.
