If IG Walpin’s firing came from Obama, and I think it did, that is an impeachable offense. Look for Darrell Issa to investigate this come Jan 2, 2011.
I suspect that setting the basis of an impeachment hearing and pulling the fangs of this administration may be what is in the works.
I doubt that Fine will be allowed to proceed. I suspect that he will carefully document the obstructions placed before him prior to his dismissal; ala, Walpin’s dismissal. Such an act, along with the DOJ actions relative to Arizona SB1070, including lack of enforcement of existing Federal laws, would give plenty of grist to impeachment proceedings.
