Democrats will control both houses of Congress come January, but analysts see limits to what they can change about federal policy.

The Senate flip is the biggest check on Trump’s campaign against the Fed, as there’s little prospect that a Democratic Senate would confirm a replacement for Gov. Lisa Cook.

The political battles over data centers move from Washington to statehouses in Texas, Ohio, and Georgia, where new governors support curtailing their growth.

A blue wave swept Republicans from power in both chambers of Congress Tuesday, but voters may find that the White House still holds sway over many of the policies that fueled their discontent.

Democrats took the House and Senate Tuesday, flipping Republican Senate seats in states including Texas, Ohio, and Kansas. President Donald Trump said Wednesday he’d work with the new Congressional leaders, but reminded them he could send their bills back “with a nice stamp veto.”

Economists spent Wednesday making a similar point. The size of the win “does not change too much for the near-term policy outlook,” Stephen Brown of Capital Economics wrote to investors, citing the Senate filibuster and Trump’s veto power as limiting Democrats’ ability to pass bills that turn into law.

Still, the wave of Democratic victories changes who writes the spending bills, who votes on new Federal Reserve board members, and potentially where new data centers get built. Here’s what shifted with the election.

Tariffs

House Democratic leader Hakeem Jeffries has said he plans votes in the first 100 hours of the new Congress to restore expired Affordable Care Act subsidies, reverse cuts to Medicaid, and challenge Trump’s tariffs. On Wednesday, Jeffries said Democrats plan to “battle the administration.”

Undoing the Trump tariffs could prove the most difficult.

After the Supreme Court struck down Trump’s emergency tariffs in February, the administration rebuilt them under Section 301 of U.S. trade law. That authority doesn’t require action from Congress. Goldman Sachs said it expects Democrats to succeed in cutting duties on goods from some countries such as Canada, but Trump could answer with new levies, leaving the effective tariff rate much the same.

Gas Prices

On Wednesday, Vice President JD Vance put most of the blame for his party’s defeat on the Iran war. WTI crude futures, the U.S. oil price benchmark, were down 8% Wednesday afternoon amid the shift in electoral fortunes.

The war set off an oil supply shock that sent gas prices above $4 a gallon for much of 2026. The average price at the pump stood at $4.12 Wednesday, according to AAA, compared with $2.98 on Feb. 28, when the U.S. and Israel first struck Iran.

Congress could work to end the Iran war by attaching conditions to Pentagon funding, refusing to pass a continuing resolution, and forcing votes under the War Powers Resolution. The war has cost about $47 billion so far.

The Federal Reserve

The Democratic takeover of the Senate matters most for the Fed. Trump can’t add allies to the Fed’s seven-member board without Senate confirmation. The president’s push to fire Gov. Lisa Cook continues, with a White House hearing set for Thursday. But there’s “next to no prospect” of a Democratic Senate confirming a replacement, Reuters reported.

Former Chair Jerome Powell’s term as governor ends in January 2028, and a Democratic Senate will decide who fills his seat.

Data Centers

Democratic control of Congress is “less likely to change the outlook for data center and AI regulation,” which still needs bipartisan support, Goldman’s economists wrote. The main action is in the states.

Texas Gov.-elect Gina Hinojosa campaigned on a moratorium on new data centers in the state, whose buildout has helped boost the economy during the second Trump administration. Ohio’s Amy Acton, who beat Republican Vivek Ramaswamy, backs a conditional pause. In Georgia, which leads the nation in new data-center construction, Gov.-elect Keisha Lance Bottoms also supports a moratorium, and Democrats also flipped the state utility commission, which oversees how they connect to the electricity grid.

Such policies “could make it slower and more expensive” without derailing the AI buildout, Bank of America economist Stephen Juneau wrote.

Analysts at Oxford Economics say that local opposition only relocates data center projects, but won’t end their buildout.

The Federal Budget

Federal funding runs out Dec. 11, and the lame-duck Republican Congress will still be in control then. Goldman said it expects Democrats to use the deadline and next year’s debt ceiling to extract concessions on tariffs, spending cuts, and Iran. Goldman estimates that reversing part of last year’s cuts could add about 0.25% of GDP to spending in 2027.

“Blocking new spending is not the same as reducing the existing deficit,” Andrew Jackson, head of investments at Vontobel, wrote in an investor note.
