Well, he is correct in that it would have be historic. A bigger opportunity for Pence right now would be to have some balls and a backbone, call out Trump for the criminal, insurrectionist, and traitor that he is, and lead the Republican party back to its so-called morality, law-and-order, and "character matters" roots. I'm not a fan of Pence by any means (I totally disagree with him on nearly every issue), but this is the real historic tragedy of Pence and his political career.
The "Law and Order" party is now cool with all laws being subject to a popularity contest.
