You really think Arnold's knuckleheaded enough to include "Hasta La Vista" in his stump speeches? Also, are you sure you aren't rooting for Bustamove to win?
He's already doing that. He used several movie one-liners on Leno, and everytime he has cameras on him he throws in something. I saw one press conference where he said "I'll be back" as he left the microphones. Maybe it's all scripted, but he'd better nip it in the bud; it just cheapens his position more and more.
