With just under a month to go until Election Day, financial decisions made by both parties appear to suggest the question being asked is not if Democrats take control of the House, but how large the majority may be.

Currently, Republicans hold a narrow 218-214 seat advantage. In February 2025, the Cook Political Report's initial ratings for the midterms found a small slice of 39 races listed as competitive, with 18 classified as "toss-ups."

That topline number has shifted, with Cook currently listing 43 districts as competitive, including 22 toss-ups. But beyond that, under the hood, Democratic and Republican groups are marshalling hundreds of millions of dollars to influence an electoral landscape that is much larger.

An NPR analysis of both parties' campaign targets, future ad reservations and outside spending by Trump-aligned super PACs finds more than 90 districts where resources are being committed in the closing weeks of the midterms.

Here's a look at the types of races that will decide who controls the House in 2027.
