Just realize that she is a certified liar, and not a very good one either.
One who lies on occasion is not a liar; a liar is one who habitually lies. Is Mrs. Clinton a congenital liar as the late William Safire claimed in a 1996 NYT opinion piece? That's rather a stretch: surely the multiple modes of her mendacity are not innate in her. She is better described as a strategic liar: lying is part of her strategy of self-advancement. She will lie whenever it is in her interest to do so. The end justifies the means.
But there is nonetheless something in her pattern of mendacity that smacks of pathology. Why did she lie about her ancestry given how easy is the exposure of such a lie? That suggests either pathology or an overweening hubris, as if she can get away with anything. She is naked AMBITION in a pants suit she fancies is bullet-proof. We shall see. Just don't underestimate her and the machine behind her.

It has been said of Bill Clinton that he'd rather climb a tree and tell a lie than stand on the ground and tell the truth. Hillary continues the family tradition. One of her latest untruths is that all four of her grandparents came to the U.S. as immigrants when only one of them did. She lied, brazenly, about something easily checked. To prolong the arboreal metaphor, why would she perch herself far out on a limb so easily sawn off? Beats me.
