Bernie Sanders

This week's Democratic debate seemed to be the noisiest yet. And The Internet did not like that.

At the Vermont independent's rally in New York on Wednesday night, one of the warm-up speakers criticized "corporate Democratic whores." But Thursday morning, Sanders said that was "inappropriate."

Oregon Democrat Jeff Merkley has backed Sanders, which could help him in Oregon's May 17 primary. Hillary Clinton has far more endorsements from Congress — a big part of her superdelegate lead.

"Demographics are destiny" has almost become a political cliché, but, so far in this campaign, it's holding true. That gives some clues for how people might vote in the New York primary in a week.

The Associated Press projects that the state will be the latest in a string of wins for the Vermont senator in the West. But the path ahead against rival Hillary Clinton is expected to get rockier.

The presidential candidate took a two-stop ride on the New York City subway this week. It seemed to be a play at the authentic, but it may have turned out to be anything but.

Supporters of Bernie Sanders' presidential campaign have been calling, emailing and tweeting so-called superdelegates who back Hillary Clinton, to try to convince them to switch sides.

Bernie Sanders plans to attend a Vatican conference about social, economic and environmental issues next week. Sanders says he's a "big, big fan of the pope" for "talking about the idolatry of money."

Ted Cruz hopes support from Scott Walker and the state's influential talk radio contingent can help him topple Trump. Meanwhile, Bernie Sanders hopes the state's progressive bent bends for him.

Sanders and his supporters are trying to change America, not the positions of another candidate. But his issues are helping to define the Democratic primary.
