Another day another insane comment that would have tanked any other candidate...yall remember when that dude yelled funny and it tanked his whole political career? I am starting to miss those days.
And it was because the microphone recording him wasn't picking up how loud the crowd was. The yell sounds fine if you hear it with the crowd noise as Dean was hearing it.
"America First" was the slogan of the American Nazi party before WWII. His similar phrase, considering the things he marries it to, has got to be deliberate.
