What will be interesting is if the undecideds shift significantly for or against, whether people will still be describing a great fracture

"fractured" means exactly what it means. If the undecideds shift against then the movement will no longer be fractured, an overwheliming majority now being in clear opposition.

Ummm, you lost me at "an overwhelming majority now being in clear opposition." What part of "undecided" shows clear opposition?
