Former HP chief executive Carly Fiorina, relegated to the undercard GOP presidential debate on Thursday night, came out swinging for Hillary Clinton. And it got very personal.

During the debate, Fiorina said pointedly that "unlike another woman in this race, I actually love spending time with my husband."

The comment was pretty transparently about Clinton, yet Fiorina was repeatedly asked in subsequent interviews: What did she actually mean by that? And what does she know about the Clinton marriage that everyone else doesn't?

To answer those questions, Fiorina has repeated that Hillary and Bill Clinton have "craved power their whole lives." But pressed on MSNBC's "Morning Joe" on Friday morning, Fiorina got far more blunt.

"If my husband had done some of the things Bill Clinton had done, I would have left him long ago," Fiorina said. "So, yes, I think it's all fair game."

To recap: Former president Bill Clinton is back on the campaign trail for his wife in Iowa and New Hampshire. Meanwhile, businessman and GOP candidate Donald Trump became the first candidate in this race to say outright -- at least in the 2016 election -- that allegations of sexual misconduct in Bill Clinton's past would be fair game in his wife's campaign.

On the other hand, Fiorina's comments suggest that it isn't Bill Clinton's behavior, but rather Hillary Clinton's decision to stay in the marriage that will be grounds for political attacks.

During the undercard debate, Fiorina went to great lengths to stress how her marriage differed from Clinton's.

"My husband, Frank, that I mentioned, I love spending time with," Fiorina said during her closing statement, apropos of nothing. "He's down there. He was real excited the other day because in New Hampshire, he was introduced as my eye candy."

"You know, everybody out there watching knows this," Fiorina continued. "You cannot wait to see the debate between me and Hillary Clinton. You would pay to see that fight."
