Republican Party
US centre-right governing party; split between MAGA insurgents and the establishment this cycle.
The Supreme Court struck down federal caps on the Republican Party's coordinated spending with its own candidates, 6-3 in NRSC v. FEC on 30 June 2026, even as the party's own primary money keeps losing to MAGA insurgents it did not back.

US Midterms 2026Background
The Republican Party controls both chambers of Congress and the presidency under Donald Trump's second term, yet unified government has not produced a unified war policy. The Pentagon's Iran supplemental, cut from an original $200bn request to an expected $80-100bn, has no scheduled vote and no congressional war authorisation months into the conflict .
Founded in 1854, the party's foreign-policy Coalition has inverted since the Iraq War era. A non-interventionist wing, including Marjorie Taylor Greene and Tucker Carlson, has called the Iran war a betrayal of the America First platform, even though polling puts support for the war at 85-90% among self-identified MAGA voters . The same fault line runs through the 2026 primaries, where establishment money has repeatedly failed to protect favoured incumbents from insurgent challengers.
The through-line for 2026: formal control of Washington has not translated into a unified Coalition, on foreign intervention or on primary loyalty.
The party's spending caps just vanished
The Supreme Court struck down federal caps on party-to-candidate coordinated spending, 6-3 in NRSC v. FEC on 30 June 2026, a case the National Republican Senatorial Committee brought against the Federal Election Commission . The old caps had run as high as $4m per Senate race and forced outside groups like the $342m Senate Leadership Fund to spend independently rather than in coordination with campaigns.
The NRSC told campaigns the same day it would fold its independent-expenditure unit into fully coordinated spending, since coordinated dollars buy up to 13 times more broadcast airtime per dollar . Analysts expect all four national party committees to build similar joint vehicles before November, but the party's own Senate Arm moved first.
The party's own insurgents keep winning
Ken Paxton beat incumbent John Cornyn 63.8% to 36% in the Texas Senate runoff on 26 May 2026, despite Cornyn's side outspending him roughly nine to one . Fellowship PAC, a crypto-aligned committee tied to Tether, had already put $1.75 million behind Paxton by 7 May while reporting only $11 million raised against a publicly claimed $100 million war chest .
The same pattern repeated in early June, when MAHA-aligned challengers beat two more establishment-linked governor hopefuls with NRCC ties. Trump's late endorsement, not the party's own spending advantage, decided the marquee Texas race.
