I guessing here… but Jeb probably dropped the Murray name because it is an NRO get together, and of course Murray is one of their favorites.

It reminds me of his brother, way back in the 1999/2000 debates, when GWB would claim the Bible is his favorite book and Jesus who inspired him most.

GWB new he had to get the Bible thumpers on board.

And now, today, Jeb knows he needs the white nationalists, at least to keep them from chopping at him.
