Washington Post-Ipsos poll shows Democrats leading Republicans for U.S. House, 48% to 45%

Democrats are maintaining a slim edge in their bid to win back control of the U.S. House, according to a new Washington Post-Ipsos poll released Saturday. The survey of registered voters found 48 percent said they would support Democratic candidates, while 45 percent said they would support Republican candidates.

The poll’s margin translates into a three-point advantage for Democrats among registered voters, a lead that suggests the contest for the House majority is likely to hinge on turnout and district-level competition rather than a large national swing, according to the figures reported by The Hill.

The Washington Post-Ipsos results arrive as both parties seek to define the House election as a referendum on national conditions while also focusing on local priorities. The reported topline numbers, however, indicate that voters remain closely divided on which party should control Congress’s lower chamber.

The poll also underscores how small shifts in voter preferences can carry significant implications for House control because the majority depends on who wins individual seats across districts rather than on statewide or nationwide outcomes.

For Democrats, the reported 48 percent share of voter support aligns with recent party messaging that they still have a viable pathway to gaining the House majority. For Republicans, the 45 percent figure provides a counterweight, keeping pressure on Democrats to translate their advantage into concrete wins rather than rely on a modest lead at the national level.

The House elections are expected in November, with the final seat distribution determined by voters in each district. The poll’s narrow margin means that both parties’ prospects are likely to be sensitive to any changes in voter engagement and preferences between now and Election Day, based on the reported numbers.
