What is the constitutional crisis that you refer to?  The only unconstitutional act I have seen in recent times is the Senate refusing to even give a hearing to the President's choice for the Supreme Court.  I guess voting in Hilary may lead to the Republicans in the Senate further violating the Constitution based on recent talk of not giving hearings to any of her choices, but I haven't heard any proposal or a threat of something that would suggest that Clinton would be the one violating the Constitution.
