Overview:

As Congress returns for the June legislative session, Republicans hold narrow majorities in both chambers, a slim two-vote margin in the House and a 53-45 Senate advantage complicated by internal party divisions. Leadership is racing to advance a packed agenda before the August recess, including FY2027 appropriations, two reconciliation bills, and major reauthorizations for the Farm Bill, Water Resources Development Act, and Surface Transportation. Meanwhile, the 2026 midterm landscape is taking shape, with Democrats well-positioned to retake the House and mounting credible challenges for Senate control.

Current Voting Margins in Congress

In the House of Representatives, Republicans are holding a very slim majority with 217 members and one Independent, who caucuses with Republicans, while the Democrats have 212 members. Additionally, there are currently five unfilled vacancies due to three Democrats and two Republicans leaving Congress in 2026. Three special elections are scheduled for this summer to fill the vacancies from Georgia and California. The current voting margins in the House means that Speaker Mike Johnson can only afford to lose two votes and still pass legislation along party lines.

In the Senate, Republicans have, on paper, a wide margin with a majority of 53 members compared to 45 Democrats and two Independents who caucus with the Democrats. Senate Majority Leader John Thune can afford to have three defections while still passing legislation on party lines with Vice President JD Vance as the deciding vote. However, President Trump’s primary election ousting of several long-serving Republican Senators, and public feuds with others, has made it increasingly difficult for Thune to keep enough Republicans aligned.

Issues at Stake

Republican leadership in the House and Senate are looking to push through multiple large legislative priorities before the August recess, including a slate of FY2027 Appropriations Bills, potentially two reconciliation bills, and multiple reauthorizations for the Farm Bill, the Water Resources Development Act and Surface Transportation Reauthorization.

Most of the focus recently has been on the reconciliation bills after attachments for ballroom funding and the “anti-weaponization” fund cast the process into upheaval. Republicans will try to pass some version of Reconciliation 2.0, designed to secure funding for DHS and ICE, and pick up Reconciliation 3.0 later in the summer. Historically, a third budget reconciliation has never been passed in a calendar year, and Republican leadership faces an uphill battle achieving it given the legislative setbacks caused by President Trump’s funding attachments. Congressional Republicans widely opposed both funding add-ons, and an Economist/YouGov national poll found that 52% of Republicans opposed the fund, leading the Trump Administration to drop the DOJ fund while Senate Republicans omitted funding for the ballroom from the second reconciliation bill.

The Senate has not started the markup process for the FY2027 Appropriations bills, while the House has a mixture of some that are out of committee and some that have not begun the process.

Surface Transportation Reauthorization passed out of the House Transportation and Infrastructure Committee 62-2 after markup and now awaits a full House floor vote. However, the Senate must advance its own bill across four separate committees before the two chambers can negotiate a final product. With the current transportation authorization expiring September 30^th a short-term extension is increasingly likely.

The Water Resources Development Act is still being worked on in the House Transportation and Infrastructure Committee, and the Farm Bill passed the House in late April, though the Senate has expressed interest in making changes given controversial cuts to food assistance programs, with a Senate draft expected sometime in early June.

Campaign Landscape

House

As the November elections approach and the dust appears to be settling on the mid-decade redistricting wars, Democrats remain in a strong position to retake control of the House only needing a net-gain of three seats. While that number will effectively grow to around 10 seats given Trump and Republicans’ redistricting push, the party out of power has historically flipped far more seats than Republicans are likely to gain through redistricting. In 2018 during Trump’s first midterm election cycle in office, Democrats flipped 40 seats.

Aside from the redistricted seats in California, Democrats will be targeting seats in New York, Nebraska, and Pennsylvania that went for Kamala Harris in 2024 but elected a Republican representative. Additionally, they have been focusing efforts on flipping other battleground seats in Arizona, Colorado, Michigan, and New Jersey. On the other side, Republicans are looking to capitalize on redistricting wins in Florida, Texas and other states across the south to curb predicted Democratic gains in California and New York. Republicans’ best opportunity to pick up other seats likely will come from purple districts in Washington and Ohio.

Senate

In the Senate, the situation for control of the body after the midterm elections is a little more straightforward. Given the margins, if the Democrats want to take control of the Senate they need to keep all their seats and pick up four to reach 51. Republicans have an easier path to keeping control as they can afford to lose three. In Georgia and New Hampshire, incumbent Jon Ossoff and expected nominee Rep. Chris Pappas, have both been holding consistent polling leads outside the margin of error. Michigan appears to be the seat most in danger for Democrats with different polling running close to even.

As for potential Democratic pickups, North Carolina looks increasingly likely given former governor Roy Cooper’s popularity and Maine is in play with progressive Graham Platner trying to oust longtime incumbent Susan Collins. Texas remains in play for Democrats after Trump’s backing of Ken Paxton who has largely polled even or slightly behind Democratic nominee James Talarico, but it has been decades since Democrats won statewide election there. Ohio remains a tossup and Sherrod Brown will likely need to pull off a critical flip for Democrats if they want to take control of the Senate. Additionally, Democrats are targeting a potential upset in Iowa, looking to capitalize on economic uncertainty to win a Senate seat for the first time since 2008. Nebraska and Alaska are other targets for Democrats to be options to offset a loss somewhere else.

Predictions

Ultimately, the math is favorable for Democrats in the House. Even accounting for Republican redistricting gains, Democrats are likely within striking distance of a House majority if historical midterm trends hold. In the Senate, it is still more likely that Republicans will lose a few seats but remain in control, however continued in-fighting and the President’s dropping approval rating could change that outlook.

As always, the political landscape can shift dramatically in the months ahead. Economic conditions, unexpected events, and the outcomes of ongoing legislative battles will all shape how voters assess both parties heading into November. Campaigns are already adjusting their messaging and resource allocation as new polling emerges, and recruitment battles for key races are far from settled. Stay tuned for continued updates as the summer legislative sprint unfolds, primaries are finalized, and the contours of the 2026 midterm map come into sharper focus.
