Gingrich:

Now that we have that out of the way, let’s talk about whether as a historian I can talk about how the Declaration of Independence was written, what Thomas Jefferson stands for, and whether it is good for American families to go on a walking tour of Washington to see historically the absolute fact that the Founding Fathers were deeply committed to the idea our rights come from God.”
I asked Gingrich if he were the most effective messenger, considering his behavior.

“You’ll have to make that decision.”

I did.

It’s not about the message. Just the messenger.

What the Declaration of Independence has to do with Belgian Education Policy in the Congo is an open question, and would have been fun to ask, if for no other reason than to deflate the obnoxiousness.

It doesn’t mean that Newt is unreasonable to talk to, but his professional expertise isn’t in American History and claiming that as a credential in such a case is weak.
