The Great One Mark Levin had simular observations on his Friday show. There is much for her to do if she wants to be a serious contender and go up against the old Republican beltway horses.

The Mark Levin show from July 3rd is Worth listening to.
My personal speculation? I think Levin knew the announcement was coming.
