After a testy debate on NY1 on Thursday, the Democratic presidential candidates embarked on somewhat unchartered campaign territories. Our Josh Robin explains.

It was the first time in recent memory that a presidential candidate visited New York public housing.

The city's housing authority is short a staggering $17 billion in major repairs, a hole that Hillary Clinton promises to address if elected.



Robin: Why should people feel faith within you that you can improve things across the city?

Clinton: Well, when we think about all of the people who live in NYCHA housing — they're fellow New Yorkers, they're Americans….We need to be supporting better housing, and having the federal government fulfil its responsibility to NYCHA is one way to do that."



Clinton says her plan marks $125 billion for affordable housing nationwide, and it boosts incentives for affordable housing development.

At the Vatican, Sen. Bernie Sanders spoke more generally.

"Speculation, illicit financial flows, environmental destruction, and the weakening of the rights of workers is far more severe today that it was a quarter-century ago," the Democratic presidential candidate said.

Sanders didn't meet with Pope Francis. Despite a competitive stateside primary, he says he didn't want to pass up a chance to speak on income inequality at a global forum.

He left shortly after Thursday night's event in Brooklyn.

The debate was more of a raucous, confrontational forum, raising questions about whether the party will ultimately unify around whoever the nominee is.

Clinton shrugged that off. "New Yorkers had a chance to see the contrast between myself and Senator Sanders, and I hope that people will come out and vote for me on Tuesday," Clinton said.

Clinton is scheduled to campaign and raise money in California this week, including at two high-dollar events with actor George Clooney and his wife Amal.
