He went to Dallas to clear his mind and open it up to the world. It was a mind blowing experience for him

Literally

He wanted to have a clear mind coming into the 1964 election, and he needed to appear open minded to the public. His brain was exploding from all the things he had to do when he got to Texas, but he remained calm and allowed his head to expand.

He took that mind opening nugget well huh
