After the November elections ushered in a new era of unified Republican governance in Washington, Democratic leaders across the country are once again preparing to lead the resistance to Donald Trump’s second-term agenda.

California’s governor, Gavin Newsom, said he would convene a special legislative session next month to “safeguard California values and fundamental rights”.

Washington state’s governor-elect, Bob Ferguson, who is currently the state’s attorney general, said his legal team has been preparing for months for the possibility of a second Trump term – an endeavor that included a “line-by-line” review of Project 2025, the 900+ page policy blueprint drafted by the president-elect’s conservative allies.

And the governors of Illinois and Colorado this week unveiled a new coalition designed to protect state-level institutions against the threat of authoritarianism, as the nation prepares for a president who has vowed to seek retribution against his political enemies and to only govern as a dictator on “day one”.

“We know that simple hope alone won’t save our democracy,” the Colorado governor, Jared Polis, said on a conference call announcing the group, called Governors Safeguarding Democracy. “We need to work together, especially at the state level, to protect and strengthen it.”

With Democrats locked out of control in Washington, many in the party will turn to blue state leaders – governors, attorneys general and mayors – as a bulwark against a second Trump administration. For these ambitious Democrats, it is also an opportunity to step into the leadership void left by Kamala Harris’s defeat.

Progressives such as Newsom and the Illinois governor, JB Pritzker, are viewed as potential presidential contenders in 2028, while Democratic governors in states that voted for Trump such as Josh Shapiro of Pennsylvania, Andy Beshear of Kentucky and Gretchen Whitmer of Michigan are seen as models for how the party can begin to rebuild their coalition. And Tim Walz, Harris’s vice-presidential running mate, returned home to Minnesota with a national profile and two years left of his gubernatorial term.

Leaders of the nascent blue state resistance are pre-emptively “Trump-proofing” against a conservative governing agenda, which they have cast as a threat to the values and safety of their constituents. As a candidate, Trump promised to carry out the “largest deportation operation in American history”. In statements and public remarks, several Democrats say they fear the Trump administration will seek to limit access to medication abortion or seek to undermine efforts to provide reproductive care to women from states with abortion bans. They also anticipate actions by the Trump administration to roll back environmental regulations and expand gun rights.

“To anyone who intends to come take away the freedom, opportunity and dignity of Illinoisans, I would remind you that a happy warrior is still a warrior. You come for my people – you come through me,” Pritzker said last week.

Unlike in 2016, when Trump’s victory shocked the nation, blue state leaders say they have a tested – and updated – playbook to draw upon. But they also acknowledge that Trump 2.0 may present new and more difficult challenges.

Ferguson said Trump’s first-term executive actions were “often sloppy”, which created an opening for states to successfully challenge them in court. Eight years later, and after studying Project 2025 and Trump’s Agenda 47, he anticipates the next Trump White House will be “better prepared” this time around.

Pritzker said Trump was surrounding himself with “absolute loyalists to his cult of personality and not necessarily to the law”. “Last time, he didn’t really know where the levers of government were,” the governor said on a call with reporters this week. “I think he probably does now.”

The courts have also become more conservative than they were when Trump took office eight years ago, a direct result of his first-term appointments to the federal bench, which included many powerful federal appeals court judges and three supreme court justices.

The political landscape has also changed. In 2016, Trump won the electoral college but lost the popular vote. Despite Republican control of Congress, there were a number of Trump skeptics willing – at least initially – to buck the president during his first two years in office.

This time around, Trump is all but certain to win the popular vote, and he made surprising gains in some of the bluest corners of the country.

Though the former president came nowhere close to winning his home state of New York, he made significant inroads, especially on Long Island. At a post-election conference last week, New York’s Democratic governor, Kathy Hochul, struck a more neutral tone. Hochul, who faces a potentially tough re-election in 2026, vowed to protect constituents against federal overreach, while declaring that she was prepared to work with “him or anybody regardless of party”.

In New Jersey, where Trump narrowed his loss from 16 percentage points in 2020 to five percentage points in 2024, the Democratic governor, Phil Murphy, acknowledged the result was a “sobering moment” for the party and country. Outlining his approach to the incoming administration, Murphy said: “If it’s contrary to our values, we will fight to the death. If there’s an opportunity for common ground, we will seize that as fast as anybody.”

Progressives and activists say they are looking to Democratic leaders to lead the charge against Trump’s most extreme proposals, particularly on immigration.

“Trump may be re-elected but he does not have a mandate to come into and rip apart our communities,” said Greisa Martínez Rosas, the executive director of United We Dream Action, a network of groups that advocate for young people brought to the US as children, known as Dreamers.

She called on state and local officials, as well as university heads and business leaders, to “use every tool at their disposal” to resist Trump’s mass deportation campaign, stressing: “There is a lot we can do to ensure Trump and his cabinet are not successful in their plans.”

State attorneys general are again poised to play a pivotal role in curbing the next administration’s policy ambitions.

“The quantity of litigation since the first Trump administration has been really off the charts – it’s at a new level,” said Paul Nolette, a political scientist at Marquette University in Wisconsin. “I fully expect that to continue in Trump 2.0.”

There were 160 multi-state filings against the Trump administration during his four years in office, twice as many as were filed against Barack Obama during his entire eight-year presidency, according to a database maintained by Nolette.

Many of the Democratic lawsuits succeeded – at least initially – in delaying or striking down Trump administration policies or regulations, Nolette said. Attorneys general can also leverage their state’s influence and economic power by entering legal settlements with companies. States have used this approach in the past to “advance their own regulatory goals”, Nolette said, for example, forcing the auto industry to adopt stricter environmental regulations.

In a proclamation calling for a special session next month, Newsom asked the legislature to bolster the state’s legal funding to challenge – and defend California against – the Trump administration. Among his concerns, the California Democrat identified civil rights, climate action, LGBTQ+ rights, reproductive rights, as well as Trump’s threats to withhold disaster funding from the state and the potential for his administration to repeal protections shielding undocumented immigrants brought to the country as children from deportation.

Trump responded on Truth Social, using a derisive nickname for the Democratic governor: “Governor Gavin Newscum is trying to KILL our Nation’s beautiful California. He is using the term ‘Trump-Proof’ as a way of stopping all of the GREAT things that can be done to ‘Make California Great Again,’ but I just overwhelmingly won the Election.”

Democratic leaders in battleground states that Trump won are also calibrating their responses – and not all are eager to join the resistance.

“I don’t think that’s the most productive way to govern Arizona,” the state’s Democratic governor, Katie Hobbs, told reporters this week, according to the Arizona Capitol Times. Hobbs, who faces a potentially difficult re-election fight in 2026, said she would “stand up against actions that hurt our communities” but declined to say how she would respond if Trump sought to deport Dreamers or to nationalize the Arizona national guard as part of his mass deportation campaign.

The state’s Democratic attorney general, Kris Mayes, who also faces re-election in two years, drew a harder line against Trump, vowing to fight “unconstitutional behavior” and protect abortion access, according to Axios. In an interview on MSNBC, Mayes said she had “no intention” of dropping the criminal case against allies of the former president who attempted to help Trump overturn Biden’s victory in the state.

Yet she insisted there would be areas of common ground. She urged Trump to revive a bipartisan border deal that he had previously tanked and called on the next administration to send more federal resources and agents to help combat the flow of fentanyl into the US.

With Democrats locked out of power in Washington, the new Indivisible Guide, a manual developed by former Democratic congressional staffers after Trump’s election in 2016 and recently updated to confront a new era of Maga politics, envisions a major role for blue states.

“Over the next two years, your Democratic elected officials will make choices every single day about whether to stand up to Maga or whether to go along with it,” the Indivisible guide states. “Your spirited, determined advocacy will ensure that the good ones know they’ve got a movement behind them as they fight back – and the bad ones know they’re on notice.”

Among the examples of actions blue state activists can demand their leaders consider, it suggests establishing protections for out-of-state residents seeking abortion access or gender-affirming care; refusing to cooperate with federal immigration enforcement and forging regional compacts to safeguard environmental initiatives, data privacy and healthcare.

Democratic leaders at every level and across the country – even those in purple or red states – can serve as “backstops for protecting the democratic space”, said Mary Small, chief strategy officer at Indivisible.

“The important things are to be proactive and bold, to be innovative and to work with each other,” she said. “I don’t think everybody has to have all of the answers right now, but to have that intention and that commitment and to not shrink down in anticipation of a more oppressive federal government.”
