Is Jeb Bush's campaign in Pickett's Charge mode?

In a story that appeared in Saturday’s New York Times, an “anonymous ally” to Bush described the former Florida governor’s new campaign manager, Danny Diaz, using a Civil War analogy:

“By hiring Mr. Diaz, Mr. Bush wanted to send a clear signal that ‘the culture of the Bush operation will now be a Pickett’s Charge engagement campaign with his main opponents,’ according to one Bush ally.”

The problem with that reference? Pickett’s Charge was the last-ditch push by the Confederates to try to win the Battle of Gettysburg. It didn’t work, and the Confederates knew beforehand that it probably wouldn’t.
