I agree with you generally, on most points, except this one: I don't think or believe Biden would have eventually rightfully claimed the presidency even had Pence succumbed to Trump's pressure. You see, Trump wanted Pence to either follow his orders, vacate the Capitol-- or die. In any of these scenarios Trump would have then declared martial law and invoked the Insurrection Act. He would then have dissolved Congress, ordered the Army to "protect" the city, especially all government buildings and institutions, "suspend" the Constitution (as a "war" measure)...and then followed Putin's and Erdogan's example: Declare himself "president for life."
