You're absolutely correct, no laws broken. (No sarcasm or any other bullshit, it is what it is.)
I think, though, it is grounds to have him forced to take a cognitive exam and get thorough mental, psychological, and physical exams. Anyone who needs to have a crib note to remind themselves about their own "moral outrage" doesn't have both oars in the water.
If that man is your gramps in a rocking chair on the back porch, then no harm no foul. When that man has access to our nation's nukes and is our commander in chief then that's a BIG F**KIN' PROBLEM.
No, it's not grounds for impeachment, but it is grounds to invoke the 25th amendment. If Harris and Pelosi had any integrity they'd start it immediately and if the voters that picked Biden had any integrity they'd support that. It's obvious that Biden is a puppet and shouldn't be criminally prosecuted for that, but his puppet masters should.
