MANCHESTER, N.H. -- One year before New Hampshire voters cast their ballots in the state’s high-profile presidential primary, U.S. Sen. Elizabeth Warren traveled to the Granite State Saturday to test out her expected 2020 campaign’s message.

The Massachusetts Democrat, who recently formed a committee to look at a White House run, offered a preview of the themes that will likely dominate her 2020 campaign during an afternoon “organizing event” at Manchester Community College.

Flanked by her husband, Bruce Mann, and dog, Bailey, Warren highlighted her humble origins growing up in Oklahoma. She stressed that she’s “in this fight” out of gratitude for the opportunity the United States gave her to rise from being the daughter of a janitor to a United States senator.

“I am grateful to America. I am grateful to America, but I am also deeply determined. I believe in an America where we build the opportunities, not just for the children of the rich and the powerful, but that we build opportunities for all of our children," she said. “This is our moment in history, it is time to dream big, fight hard and make this country work for all of our citizens.”

Contending that her family’s struggles were not unique, the senator reiterated her push for “structural” change in Washington D.C., American politics and the country’s economic policies to help root out corruption and support working class Americans.

Warren specifically called for keeping money out of politics, ending lobbying in its current form and and forcing elected officials to publish their tax returns online, among other things.

The Democrat, in fielding questions from audience members, echoed her previous -- and controversial -- claim that America’s criminal justice system disproportionately impacts individuals of color and is “broken front to back.”

“It is up to all of us who believe in justice to make change in that system from front to back,” she said.

Warren offered that marijuana legalization is one of many policies federal lawmakers could pursue to address issues in the criminal justice system.

She further voiced support for “science" and strengthening environmental standards, restoring legal protections for domestic violence victims and safeguarding Medicaid, among other things.

John McCauley, of Bow, N.H., said he didn’t know much about Warren, but was interested to hear the Democrat’s message firsthand.

“We’re just starting to explore potential candidates and thought, well she’s close by, why not come and hear what she has to say,” he said. “She’s a senator from Massachusetts and ... sounds like she probably lines up, at least, with our views.”

McCauley said while he’s just starting to think about 2020, he is looking for a candidate who has “a more liberal, open platform.”

“We don’t line up very well with the current administration, so we’re definitely looking at 2020 for, hopefully, a change,” he said, adding that he hasn’t yet settled on supporting any one candidate.

Jennifer Bricchi, of Allenstown, N.H., meanwhile, she has long been a fan of the Massachusetts senator and is “thrilled” the Democrat is eying a 2020 White House run.

“We need a change. The way we’ve been going for the past two years is ridiculous and I’m thrilled with her. I love her ideals, I think I have the same. And, It’s just exciting to have her here in New Hampshire so soon after making her (exploratory committee) announcement,” she said.

Bricchi added that she believes Warren’s message and focus on addressing economic inequality will resonate with New Hampshire voters.

“You have people here in New Hampshire, who are, of course, going to support the Republican candidate no matter who it is, but you also have ... a lot of working class citizens here in New Hampshire that, I think, she does appeal to,” she said. “I think they’d embrace her.”

Gail Mitchell, of Rochester, N.H., agreed.

“It’s time for a Democratic aggressive leader to go to Washington and get things done quickly,” she said, offering that she sees Warren as that person.

“It’s clear Warren is focused more on her own political ambitions than helping hard-working families," RNC Spokesperson Mandi Merritt said in a statement. "Granite State voters will see through today’s dog-and-pony show for what Elizabeth Warren really is -- a phony who has repeatedly fumbled delivery on the national stage.”

A handful of protesters gathered outside Manchester Community College Saturday.

Warren announced in a New Year’s Eve video message that she had formed an exploratory committee as a prelude to a 2020 presidential run -- ending speculation that had dogged the senator throughout her 2018 re-election campaign.

Days after the announcement, Warren headed to Iowa -- another must-visit state for presidential contenders -- to meet with voters at a series of organizing events.

In addition to addressing New Hampshire voters at Manchester Community College, the senator was set to attend a private house party in Concord, her exploratory committee announced.

Warren will return to New Hampshire next month to deliver keynote remarks at the New Hampshire Democratic Party’s 60th annual McIntyre-Shaheen 100 Club Dinner.
