Do I know, for certain, that Sharon Bialek is lying about Herman Cain sexually harassing her in 1997? No, but a couple of things about her story don’t quite pass the smell test. So far four women have accused Cain, a candidate for the Republican presidential nomination, of sexually harassing them in the 1990s.

Bialek was the first to go public. Karen Kraushaar, a second accuser, has also gone public but hasn’t given any details about the alleged harassment.
