Here’s what Democrats should do: In the House and the Senate, put forth bills explicitly countering the SCOTUS decision, making Presidents criminally accountable in federal court for illegal acts done while in office, regardless of if they were impeached and convicted while in office. Call it “The Presidential Accountability Act.”
Put it out. Watch the Republicans vote against it or block it. Then put it out again. And watch the Republicans block it. Make a commercial of Joe Biden sitting at the Resolute Desk waiting for the legislation to sign. “C’mon, Republicans, whatcha waiting for?” Joe asked into the camera. “Don’t you wanna hold me responsible?”
