WORCESTER -- Contending that Massachusetts "is a state of resilience," U.S. Sen. Elizabeth Warren called on local Democrats Saturday to join her in fighting back against President Donald Trump and Republican policies.

The senator, who rallied delegates at the Massachusetts Democratic Party Convention in Worcester, took issue with the president's efforts to institute a so-called travel ban, undo the Affordable Care Act and cut budget funding for food stamps and other safety-net programs.

Although Massachusetts Democrats live in a historically blue state, she added, they "cannot escape the pain that the Trump Administration wants to inflict on working people all across the country" and must not stay silent.

Warren called on delegates and party leaders to "fight back" and show "real courage," contending that "the health, the safety, the national security of the people of Massachusetts and the United States of America are on the time."

"We have a job to do--both here in Massachusetts and across the country," the senator said. "Instead of a Trump government that works just for those at the top, we need to make this a government that works for everyone--a government that builds opportunities, not just for those at the top, but for everyone."

Those opportunities, she offered, include: addressing student loan debt, raising the minimum wage, investing in public schools, cracking down on money in politics and expanding Social Security.

Acknowledging her own spats with the president, Warren encouraged Massachusetts Democrats to fight for policies and issues they believe in, despite possible criticism or attacks they may garner from the White House.

The senator further offered that the reason Trump goes after critics boils down to one thing: fear.

"Massachusetts Democrats, there's a reason Donald Trump attacks us. There's a reason he calls us names. There's a reason he says all of you illegally voted in New Hampshire," she said. "Because he's scared of you."

Trump's biggest fear, Warren argued, "is meeting someone who will fight back."

Pointing to Massachusetts' history as a state of abolitionists, suffragettes and revolutionaries, the senator said she's confident it will "lead the fight against a dangerous bully in 2017, 2018, 2019 and 2020."

"Massachusetts is a state of resilience, compassion, leadership and, above all, hope. No, Massachusetts is not perfect ... but in this time of crisis, here in Massachusetts, we dig down and find the strength that makes us great," she said. "In a time of crisis, we fight back. And Massachusetts Democrats, I promise you this: I will fight my heart out for you."

Warren, who is seeking re-election to her Senate seat in 2018, stressed that Democrats will not back down, but rather resist, persist and win.

The issues-focused 2017 Massachusetts Democratic Convention gave delegates the opportunity to weigh-in on policies the state party should prioritize heading into the 2018 election cycle.

In addition to voting on the party's platform, delegates heard from an array of state Democratic leaders, including U.S. Sen. Ed Markey; U.S. Rep. Jim McGovern, of Worcester; Massachusetts Attorney General Maura Healey; Auditor Suzanne Bump; and state Senate President Stan Rosenberg.
