National Sentiment Tracking

Democratic challengers are significantly outraising Republican challengers in the most competitive House districts, according to a Reuters analysis of campaign finance reports. In roughly 30 battleground races, Democratic candidates targeting GOP-held seats raised about $50 million combined, more than double the roughly $20 million raised by Republican challengers in Democratic-held districts.

The early financial advantage gives Democrats momentum as they seek to flip the few seats needed to reclaim the House majority, though incumbents from both parties continue to dominate overall fundraising, and outside spending remains a major wildcard. Read More. 

Notable retirements from Congress are beginning to come out as the election year gets underway. The current total sits at 51 incumbent members (21 Democrats / 30 Republicans) of the House who have announced they are not seeking re-election. 

For context, during the first Trump term, there were 52 retirements from the House. 

MID-CYCLE REDISTRICTING FIGHT MOVES TO THE COURTS

Legal battles over congressional maps are accelerating across nearly a dozen states, with court rulings now poised to shape the House majority just months before the election. Lawsuits and redraw efforts in states including Missouri, Florida, Virginia, New York, Utah, and Wisconsin are creating uncertainty for campaigns and election officials as primary season approaches.

The most consequential case, Louisiana v. Callais, could reshape national maps by revisiting Voting Rights Act protections that influence majority-minority districts. While a decision is expected later this year, states are preparing for rapid redraws that could alter district lines on short notice. Read More.

UTAH REDISTRICTING RULING KEEPS DEMOCRATIC OPPORTUNITY ALIVE

A federal court rejected Republican efforts to block Utah’s court-ordered congressional map, clearing the way for districts that could give Democrats a viable path to one of the state’s four House seats in 2026. The map consolidates Democratic-leaning Salt Lake County rather than splitting it across multiple districts, and the court declined to intervene so close to the election calendar. The decision underscores how court rulings, even in reliably Republican states, are actively reshaping competitiveness and could influence the fight for House control. Read More.

So far, 9 Senators have announced their retirement from the chamber at the end of the current Congress. 

TEXAS GOP SENATE PRIMARY INTENSIFIES AS EARLY VOTING BEGINS

Early voting is underway in Texas’s high-stakes Republican Senate primary, where incumbent Sen. John Cornyn faces strong challenges from Attorney General Ken Paxton and Rep. Wesley Hunt in what could be the toughest race of Cornyn’s career. Recent polling shows Paxton leading with roughly 38% support, followed by Cornyn and Hunt, with a runoff widely expected if no candidate secures a majority.

The contest has grown increasingly combative, with candidates attacking one another’s records and positioning themselves as the strongest conservative voice, while heavy advertising spending and national attention underscore the seat’s importance.

Why it matters: The primary highlights ideological divisions within the Texas GOP and could shape general-election competitiveness in a critical Senate race, making the outcome consequential for national party strategy and Senate control. Read More.

MICHIGAN SPECIAL ELECTION DRAWS NATIONAL ATTENTION

Democrats are pouring resources into the May special election for Michigan’s 35th state Senate district, viewing the race as critical to maintaining control of the chamber and as an early test of voter sentiment ahead of the midterms. The Democratic Legislative Campaign Committee has labeled it a “spotlight” contest, underscoring its strategic importance.

The outcome could shape legislative power in Lansing for the remainder of the year while offering an early signal of turnout dynamics and party momentum heading into 2026. Read More.

The Supreme Court struck down the administration’s sweeping global tariffs, ruling the president exceeded emergency powers and reaffirming that Congress holds authority over tariff policy. The decision disrupts a central economic tool, raises questions about refunds on collected duties, and signals that future trade actions will face greater legal scrutiny even as the White House explores alternative tariff pathways.

Tariffs and their impact on consumer costs and supply chains remain politically salient, but future actions are likely to be more contentious and procedurally constrained. Read More.

Outside spending tied to artificial intelligence and cryptocurrency policy is rapidly scaling ahead of the midterms, signaling a new phase of issue advocacy centered on emerging technologies. Millions of dollars in ads are seeking to shape public opinion on AI regulation, with competing campaigns framing oversight as either essential consumer protection or a threat to U.S. innovation and competitiveness.

At the same time, the cryptocurrency industry has amassed a massive political war chest, approaching $200 million, to support candidates aligned with its regulatory priorities and oppose critics, underscoring its growing influence in congressional races.

Technology policy is becoming a major battleground for outside spending, with well-funded industry groups working to shape both election outcomes and the regulatory environment. As AI governance and digital asset rules move toward the center of economic policy debates, special-interest investment is accelerating the nationalization of these issues and elevating them as defining campaign narratives in 2026.
