From Blogora, this video:
I am shocked that she would ever say that she would support Hillary Clinton, but I think this is actually, for Coulter, her most well-reasoned argument I’ve ever heard her make. Clinton is, in some policies, more conservative than McCain. Additionally, Hannity’s claims that Clinton would nationalize health care and pull us out of Iraq quickly are inaccurate: She is not that liberal.
But then again, we have to put this into the context of Coulter’s rhetoric: a “shock” campaign, and this is (probably) just part of her public persona/performance: To shock and draw attention to herself. What could be more shocking that calling John Edwards a faggot? Endorsing Hillary Clinton. What would be more shocking than saying Jews need to convert to Christianity… well, perhaps not much.
