Democrats are four days from potentially winning their largest House majority since 2009, using a playbook they lifted directly from Donald Trump — the same tactics they spent years calling a threat to democracy.

The Cook Political Report shifted 14 House and Senate races toward Democrats on October 30, according to USA TODAY, with The Washington Post reporting 12 House races moved in Democrats' direction. Cook now favors Democrats in 222 House races, with 18 more rated as toss-ups. Democrats need 218 for the majority. If they win them all, they could reach 240 seats — their largest majority since 2009.

The engine behind the shift isn't some bold new Democratic idea. It's Trump's 2024 cost-of-living message, repackaged and aimed at a Republican president whose approval is cratering.

As the Anchorage Daily News reported, Democrats spent the months after their 2024 shellacking taking notes on exactly how Trump beat them — by making high costs central. Now they're running the same play. They've attacked Trump's sweeping tariffs, hammered Republicans on health care costs during the 2025 government shutdown, and recruited candidates who can talk grocery prices in swing districts.

The strategy is paying off. A Washington Post-ABC News-Ipsos poll cited by the Anchorage Daily News found 37% of Americans now trust Democrats more on the economy, versus 28% who trust Republicans — a reversal of the dynamic that carried Trump to the White House.

Three races previously rated "lean Republican" moved to toss-up, including Rep. Brian Fitzpatrick's Pennsylvania seat and Rep. Jeff Crank's Colorado district, The Washington Post reported. Ohio's 9th District and Pennsylvania's 8th — both Trump bellwethers with white blue-collar voters — shifted from toss-up to lean Democrat, according to USA TODAY.

"If the bottom completely falls out for Republicans, Democrats could flip some seats in the Lean Republican and Likely Republican columns as well," Cook House analyst Erin Covey wrote, as The Washington Post reported. Republicans are reportedly concerned about turnout in North Carolina and Pennsylvania, where Democrats look positioned to win statewide races comfortably.

Both USA TODAY and the Anchorage Daily News noted Trump's approval has been falling for months, driven by a costly war in Iran and prices that keep climbing. That's the opening Democrats are walking through. "Every dollar, every volunteer is being deployed right now, and no regrets," DCCC chair Rep. Suzan DelBene told Colorado voters last week. "Leave nothing on the table."

Republicans haven't helped themselves. The GOP held a massive dollar advantage and used mid-decade redistricting in Florida and Texas to try to shore up friendly seats, the Anchorage Daily News reported. Speaker Mike Johnson has questioned poll accuracy and insisted Republicans will hold the House. The Cook shifts suggest otherwise.

Here's what the establishment press won't dwell on: economists are skeptical Democrats can actually do much to rein in prices if they win, as the Anchorage Daily News noted. The same party that spent the Biden years telling Americans the economy was fine is now campaigning as the champion of affordability — because Trump proved the message works first.

Democrats are poised to win by admitting Trump was right about what mattered to working Americans. The open question is whether they'll deliver — or whether, like every majority before them, they'll find that campaigning on affordability is a lot easier than governing for it.
