I think the effort to force Pence to acknowledge that the Constitution DIRECTS he SHALL PRESIDE over the count of electoral votes, making him ALONE responsible for the PROPER conduct of the count... is one issue.
A more important issue might be... ensuring Pence is served with a proper notice... informing him, in a way that he cannot deny, that the “certified” electors are a product of an ongoing FRAUD. Because of that fraud being practiced: Pence should also be served with a request to see his communications with all of those who are being accused of conducting a fraud. The proper agency for making that demand, might well be the state Legislatures.
The purpose of the fraud being practiced is to either deceive or compel Pence into wrongly accepting the products of fraud in his performance of official duties. Simply exposing the FRAUD... not in public perception, but in recognition in official process... leaves him a choice of participating in the fraud, or refusing to participate in the fraud... as that is the real choice being made.
Legislatures... need to NAME the fraud, as a fraud... while taking action in addressing it... not only decertifying, and not only allowing the event in recalling those perpetrating the fraud... they should also initiate impeachment proceedings against those who are obstructing the process of proving the fraud.
You sum up the issue very well!
Since this is uncharted territory, we would be well served to have the issues brought forth now rather than after the fact. Compelling Pence to buy into an 'unlawful' slate of electors destroys any appearance of legitimacy of the electoral process. ANY member, including Pence, must be able to examine substantive claims of unlawful activities before accepting what is presented to them.
