Because the U.S. Home of Representatives voted to approve President Donald Trump’s sweeping domestic tax and spending package, many critics are questioning how the president retained the loyalty of so many congressional Republicans, with so few defections.
Simply three Republican senators – the utmost allowed for the One Big Beautiful Bill Act to nonetheless cross – voted towards the Senate model of the invoice on July 1, 2025. Within the Home, solely two Republicans voted towards the invoice, which passed the chamber on July 3.
Among other things, the invoice will slash taxes by about US$4.5 trillion over a decade and exempt people’s tips and overtime pay from federal earnings taxes.
However the invoice has been broadly panned, including by some Republicans.

The laws can also be prone to add between $3 trilion and $5 trillion to the nationwide debt by 2034, in accordance with the Congressional Funds Workplace.
The facility of the presidency
Trump will not be the primary president to bend Congress to his will to get laws authorised.
Presidential supremacy over the legislative course of has been on the rise for many years. However opposite to fashionable perception, lawmakers will not be all the time merely voting primarily based on blind partisanship.
More and more, politicians in the identical political get together as a president are voting in keeping with the president as a result of their political futures are as tied up with the president’s fame as they have ever been.
Even when nationwide polling signifies a coverage is unpopular – as is the case with Trump’s budget reconciliation bill, which an estimated 55% of American voters mentioned in June they oppose, in accordance with Quinnipiac University polling – lawmakers within the president’s get together have severe motivation to comply with the president’s lead.
Or else they threat shedding reelection.

Lawmakers more and more partisan on presidential coverage
Over the previous 50 years, lawmakers within the president’s get together have more and more supported the president’s place on laws that passes Congress. Opposition lawmakers, in the meantime, are more and more united towards the president’s place.
In 1970, for instance, when Republican President Richard Nixon was within the White Home, Republicans in Congress voted along together with his positions 72% of the time. However the Democratic majority in Congress voted with him almost as a lot, at 60% of the time, significantly on Nixon’s extra progressive environmental agenda.
These patterns are extraordinary within the trendy Congress. In 2022, for instance – a 12 months of serious legislative achievement for the Biden administration – the Democratic majority in Congress voted the same way because the Democratic president 99% of the time. Republicans, in the meantime, voted with Biden simply 19% of the time.
Elections can inform us why
Over the previous half-century, the 2 main events have modified dramatically, each within the absolutist nature of their beliefs and in relation to 1 one other.
Each events was extra mixed in their ideological outlooks, for instance, with conservative Democrats and liberal Republicans taking part in key roles in policymaking. This made it simpler to type cross-party coalitions, both with or towards the president.
A couple of a long time in the past, Democrats and Republicans had been additionally much less geographically polarized from one another. Democrats had been often elected to congressional seats within the South, for instance, even when these districts supported Republican presidents comparable to Nixon or Ronald Reagan.
A lot of this has modified in current a long time.
Congress members will not be simply ideologically at odds with colleagues in the other party – they’re extra similar than ever to other members within their party.
Districts supporting the 2 events are additionally more and more geographically distant from one another, usually alongside an urban-rural divide.
And presidents specifically have change into polarizing partisan figures on the nationwide stage.
These modifications have ushered in a bigger phenomenon referred to as political nationalization, through which native political concerns, points and candidate {qualifications} have taken a again seat to nationwide politics.
Ticket splitting
From the Sixties via a lot of the Eighties, between one-quarter and one-half of all congressional districts routinely split tickets – that means they despatched a politician of 1 get together to Congress whereas supporting a unique get together for president.
These are the same few districts in Nebraska and New York, for instance, that supported former Vice President Kamala Harris for president in 2024 however which additionally elected a Republican candidate to the Home that very same 12 months.
Because the Reagan years, nonetheless, these kind of districts that would concurrently help a Democratic presidential nominee and Republicans for Congress have gone almost extinct. At present, solely a handful of districts break up their tickets, and all different districts choose the identical get together for each places of work.
The previous two presidential elections, in 2020 and 2024, set the identical file low for ticket splitting. Simply 16 out of 435 Home districts voted for various events for the Home of Representatives and president.
Members of Congress comply with their voters
The political success of members of Congress has change into more and more tied up with the success or failure of the president. As a result of almost all Republicans hail from districts and states which are very supportive of Trump and his agenda, following the desire of their voters more and more means being supportive of the president’s agenda.
Not doing so dangers blowback from their Trump-supporting constituents. A June 2025 Quinnipiac College ballot found that 67% of Republicans help the invoice, whereas 87% of Democrats oppose it.
These electoral concerns additionally assist clarify the unanimous opposition to Trump’s laws by the Democrats, almost all of whom signify districts and states that didn’t help Trump in 2024.
Because of get together polarization in ideologies, geography and within the voters, few Democrats may survive politically whereas strongly supporting Trump. And few Republicans may accomplish that whereas opposing him.
However because the significance to voters of mere presidential help will increase, the significance of members’ talent in preventing for points distinctive to their districts has decreased. This may depart essential native issues about, for instance, distinctive native environmental points or declining financial sectors unstated for. On the very least, members have much less incentive to talk for them.
