Ignore the impeachment expungement theater entirely and focus on tracking the federal judge's ruling on the 'inappropriate content' executive order and the Iran deal announcement—both have actual governance consequences.
This is a textbook distraction play: a demand with zero legal mechanism (Congress cannot 'expunge' impeachments from the constitutional record) generating high media volume during a week with actual governance actions. The 64-point B-A margin reflects pure spectacle designed to redirect attention from the federal judge blocking his executive order and other substantive developments. Minimal constitutional damage as it's merely a demand with no enforcement pathway.
