This ¶ sums the article up pretty well:
Observing him, it quickly became clear that, like all bullies, Issa is not prepared to fight. He counts on his opponents to back down. His M.O. is to make outrageous, unsubstantiated claims, follow them with a lot of bluster, and then quietly fold at the first sign of being challenged. And here’s his “tell”: The more bombastic he is, the more he hungrily seeks out the cameras, the more he promises “explosive revelations,” the less he actually has. Bullies don’t win fights; they win defaults. Push back just the tiniest bit, and it’s all over.
Just another Repug I'd like to punch.
