Democrats build a new blue border wall

By the numbers: Democrats last held all four governorships — California, Arizona, New Mexico and Texas — in January 1979, according to National Governors Association records.

• 10 for 10: Democrats swept all 10 House districts touching Mexico for the first time since 2008, according to an Associated Press analysis.
• Three flips: JoAnna Mendoza ousted Republican Rep. Juan Ciscomani in Arizona. Bobby Pulido and Katy Padilla Stout flipped Republican-held seats in Texas.
• Four attorneys general: Democrats also won the top legal offices in all four border states, including Texas, where the party hadn't won an attorney general race since 1994.

State of play: Trump built his immigration crackdown around the southern border. He declared a national emergency on his first day back, expanded the military's role and border barriers, and launched a sweeping deportation campaign.

• Southwest border apprehensions dropped roughly 91% in the 12 months through August compared with Biden's final 12 months, according to FactCheck.org's October analysis.
• The crackdown has also reached further into American communities, with ICE arrests surging during the summer of 2026.

Zoom in: Texas Democrat Gina Hinojosa's defeat of Gov. Greg Abbott could bring the most immediate border changes.

• Abbott spent about $11 billion on Operation Lone Star, deploying state police and National Guard troops and building Rio Grande barriers, according to the Texas Tribune.
• Hinojosa, Texas' first Latina governor-elect, has questioned that spending. She can rethink state deployments and enforcement priorities, though existing laws and federal authority limit her options.
• Democrats also flipped the Texas House and elected a Democratic attorney general, giving Hinojosa allies in funding and legal battles. Republicans retained the state Senate.

The intrigue: Outgoing Texas Attorney General Ken Paxton filed more than 20 lawsuits against Democratic immigration policies and defended Gov. Greg Abbott's border crackdown.

• His Democratic successor, Nathan Johnson, has vowed to challenge unconstitutional federal border tactics — potentially turning the office from a powerful Trump ally into an adversary.

What we're watching: Several Democrats newly elected to represent border districts in Washington campaigned on both strong border security and pathways to citizenship for longtime undocumented immigrants.

• Bobby Pulido, who flipped a Texas GOP-held seat, said in his launch video: "Yes, we have to get the criminals out and secure the border. But we can do that without destroying families and our South Texas economy." He also told the Texas Tribune that one of his congressional priorities will be codifying a pathway to citizenship.
• JoAnna Mendoza, who flipped an Arizona seat, also backs a strong border and legal pathways to citizenship.

That aligns with many border voters' views:

• An October N+ Univision/YouGov survey found 56% of Texas Hispanic voters thought immigration enforcement had gone too far. Yet 62% wanted border security and a pathway to citizenship for longtime undocumented immigrants pursued together — suggesting Democrats can make gains without abandoning enforcement.

Zoom out: Trump's tariffs and immigration crackdown have rattled businesses that depend on trade and shoppers from Mexico, giving Democratic governors another reason to challenge Washington.

• Laredo businesses report fewer customers, while merchants near San Diego's border crossings say tougher immigration enforcement has hurt foot traffic and hiring.
• Arizona Gov. Katie Hobbs pressed Washington over tariffs and trade uncertainty. Manufacturers near Santa Teresa, New Mexico, have put projects on hold amid tariff threats and uncertainty over trade rules.
