There's one thing that Sen. Lindsey Graham (R-S.C.) doesn't want Donald Trump to say if he loses the election in November: "It was rigged."

"I don't think it's good for democracy to have a major candidate for president doubt the outcome," he told CNN Thursday. "But being rigged means it's rigged against you, and I think Mr. Trump's fate is in his own hands."

Trump has given mixed messages on the topic — in August, he told a crowd in rural Pennsylvania, "The only way we can lose, in my opinion, I really mean this, Pennsylvania, is if cheating goes on. I really believe it." During the first presidential debate last month, he took a different stance, declaring that if Hillary Clinton wins, "I will absolutely support her."
