The Rev. Al Sharpton is hosting his annual conference in Midtown this week, and it's turned into something of a seminar on how to stop President Trump. Josh Robin filed the following report.

Everything is at stake. That's this year's theme for the Al Sharpton's first confab in the Trump era. 

"People are really ready to organize. Now, you've got to really give them the assignements," said the Rev. Al Sharpton.

Eric Holder is tackling voting rights, like laws passed in the name of combating ballot box fraud that experts agree barely occurs.

"Now, to employ the language of our president, that is how elections are officially rigged," Holder said.

This panel looked into police, with mothers of those killed by law enforcement.

Gwen Carr, Eric Garner's mother, stumped for Hillary Clinton.

"Well, when she lost, I felt like I lost too," Carr said. "But now that that didn't happen, we have to continue."

Continue, but can Trump's opponents be effectively joined? Not always, it appears.

Terry O'Neill is president of the National Organization for Women. We asked her about uniting with abortion rights opponents who also oppose Trump.

"Let me just say this. It's my job to defeat any politician who opposes women's full access to abortion care and birth control. And I'm pretty good at my job, and I will never back off from that." 

The new Democratic National Chairman Tom Perez focuses on the perceived threat.

"And then you propose budgets, they call it a skinny budget. I think of another word that begins with s that I won't use. It's a shoddy budget!" Perez said.

But Trump supporters are polled to be overwhelmingly standing with him.

"I think Democrats spend too much time conferring about how do we win some of the 46 percent of the vote that Donald Trump won."

If resisting President Trump was one backdrop, another was praising former President Barack Obama. He packed this convention when he spoke here three years ago. Halcyon days for the crowd.

A nagging question is, could life under his successor grow normal?

"Every time I think Donald Trump becomes normalized, he does something else to prove me wrong," Sharpton said.

And 100 days in, lack of legitimacy lingers. Listen closely to what state Attorney General Eric Schneiderman says about U.S. Attorney General Jeff Sessions. 

"And see it embodied in people like our so-called federal attorney general," Schneiderman said.
