Laura Belin rounded up what Iowa elected officials have said:
“Is it time to acknowledge Biden as president-elect?” [Sen. Charles] Grassley dodged: “I don’t have to – the Constitution does.”
Hughes followed up: “And do you acknowledge him as president-elect?” Grassley replied, “I follow the Constitution.”
This is a continuation of Grassley et al. pretending that the Constitution is the beginning and end of the rules and norms they must adhere to. That’s why he blocked Merrick Garland from the Supreme Court under Obama (“A majority of the Senate has decided to fulfill its constitutional role of advice and consent by withholding support for the nomination,” he said) or why he kept voting for unqualified Trump appointees. It’s a form of Originalism but for the legislative branch. And if you strip away interpretations from the Constitution, you can make it fit your raw political motives.
