You just reminded me of my favorite memory of the House Impeachment Hearings, when Rep. Rogan stated, "if someone made that argument before me when I was a judge, I'd be calling the State Bar Association asking about the status of his law license."
I am not making a legal argument, just making an observation.
The left has been making outlandish statements about Republican candidates with impunity for years, ie: October Surprises. I think this is one person (Palin)that may take them to task and actually not roll over as so many have in the past.
