The ad starts out by using names Trump has called women, including "bimbo" and "fat pig."

"A person who is very flat-chested is very hard to be a 10," a woman in the ad says at the beginning, quoting Trump.

"Look at that face — would anyone vote for that?" another woman says, quoting Trump's comments about Carly Fiorina, a former GOP presidential candidate who has now endorsed Sen.

Another woman: "That must be a pretty picture — you dropping to your knees."

"Women, you have to treat them like shit," says another.

The ad ends by saying that this is how Trump talks about our mothers, sisters and daughters.

"If you believe America deserves better, vote against Donald Trump," it says.

Our Principles PAC is an anti-Trump super-PAC run by former senior Mitt Romney adviser Katie Packer.

The PAC has aired attack ads against the front-runner including one in Florida called "Scam," which targeted Trump about Trump University.

The group is looking to stop Trump from winning Tuesday contests in states including Florida, Ohio and Illinois.
