You post:

“According to the article, this guy Martin sent “a very ugly” email”

The article states:

Adams didn’t say who wrote the email or what specifically it said about Cruz.
“It was a very ugly email,” she said. “And I really want to drop it at that, and I don’t want to be fingering the person who wrote it.”

You're right -- I misread that aspect of it. The article does not state that it was Martin himself who wrote that email.

Nevertheless, the overall point stands. Someone still wrote a "very ugly" email about Cruz (which is probably an apt-description, else it wouldn't have been a big deal), and the repercussions of that email are what caused the problem.

I don't see how that is the fault of the Cruz campaign given that they obviously didn't know about the email until someone on the Board itself gave it to them.
