Mr.Cain has at least hundreds of thousands of supporters who “get” what he says about the 2nd Amendment vs. local gun laws. I don’t understand the problem.

The problem is that whatever the Cain supporters "get", it would be nice to actually see some detailed discussion by Herman Cain that supports what they believe he thinks on the subject. He might be great on it, but as the GOA said, they don't see it in his record or his statements yet, so they need him to clarify it.
He didn’t differentiate, so it was an unsophisticated answer. If he had cited SCOTUS and either agreed or disagreed with the decision, that would have shown some familiarity with the subject, but he swung right into his libertarian kneejerk without the background knowledge or skill to give a sound answer.
