HUDSON, N.H. — In his last appearance before the primary here on Tuesday, former President Bill Clinton said he wishes “sometimes” that he wasn’t married to Hillary Clinton because then he could speak more freely.

"Sometimes when I am on a stage like this, I wish that we weren’t married, then I could say what I really think," Bill Clinton said before introducing his wife at a rally. "I don’t mean that in a negative way. I am happy."

The 42nd president, who until now had been notably restrained in stump speeches for his wife, unleashed some harsh words against her chief rival, Vermont Sen. Bernie Sanders, at a campaign stop in Milford Sunday.

“When you’re making a revolution, you can’t be too careful about the facts,” he said. Clinton also said Sanders’ supporters had launched “sexist” attacks against his wife.

The latest polls show Hillary Clinton trailing Sanders by 10 or more points in the Granite State.

At a rally earlier Monday in Manchester, in an apparent response to the attention his comments received, Bill Clinton admitted he had to be more cautious with his words.

"The hotter this election gets, the more I wish I were just a former president and, just for a few months, not the spouse of the next one because, you know, I have to be careful what I say," he said.
