Sen. Thom Tillis was fed up, and took to the Senate floor to unload on PresidentDonald Trump's megabill. As the bill cleared a key hurdle, Tillis issued a warning. He attributed his rise to U.S. senator from North Carolina to blowback against former President Barack Obama's 2010 health care law,the Affordable Care Act, which fueled crushing Democratic losses across the country. Republicans won control of the U.S. House, stopping Obama's legislative agenda in its tracks. The GOP is now rushing into similarly perilous territory, Tillis implied, by cutting more than $1 trillionfrom Medicaid. "Republicans are about to make a mistake on health care andbetraying a promise," he said.

He came out against Trump's legislation because of deep cuts to the federal health insurance program for low-income Americans, prompting the president tothreaten a primary challenge. Tillis thenannounced he wouldn't seek reelection in 2026. Tillis' experience sums up theexplosive politicssurrounding a nearly 1,000-page bill that has deeply divided the GOP. Many Republicans are touting it as a landmark achievement, but others are worried the unpopular measure hurts vulnerable people, goes against the party's working-class outreach, balloons the deficit and could cost Republicans dearly in the next election. Elon Musk, the multibillionaire former Trump adviser, is threatening to primary GOP lawmakers and even start a new political party over his deficit concerns. Looming over the debate is a president who threatens retribution against those who oppose him, and is pushing to have the legislationon his desk by July 4. Term-limited and free from facing voters again, Trump is looking for a legacy achievement. His supporters predict the bill will prove out over time. Sen.Jim Justice, R-West Virginia, compared the controversy to someone sticking their hand in a bucket of water and jerking it out.

"That's what I think will happen." The bill narrowly cleared the Senate by a 51-50 vote on July 1 - three Republicans and every Democrat opposed it ,and Vice PresidentJD Vancehad to break the tie in a dramatic flourish - after a different version earlier passed the House. It now heads back to the House for final approval, where lawmakers have expressed concerns that the spending cuts either go too far, or not far enough. Trump said July 1 it would be "wise" for Republicans to get on board. "It's a great bill," Trump said, adding: "Great for the border, great for low taxes, and I would say that they have to do it." Despite some of the GOP resistance, bucking the president is politically perilous – as Tillis experienced − and Trump appears poised for a major legislative victory. The billwould enact key campaign promisesinto law – including cutting taxes on tipped wages and overtime pay and greatly expanded deportation efforts, which would receive a massive funding increase. It also makes permanent the sweeping tax reductions Trump passed in 2017, cementing his record as a big tax cutter. Trump launched his second term with an aggressive policy agenda, but hasrelied on executive ordersthat can easily be undone if Democrats reclaim the White House. His megabill – dubbed the One Big Beautiful Bill Act - is a more lasting achievement, one that will help define his legacy. Yet like other major policy proposals from past presidents, the politics of the legislation have been difficult to navigate. Obama's health care bill divided Democrats, with 34 voting against it in the House. To help offset lost tax revenue, Trump's bill makes big cuts,most notably to Medicaid. That has some Republicans nervous. Any political victory from the bill could be short lived if it results in major blowback in the 2026 midterms. The legislation could complicate the GOP's pitch to blue collar voters. "This is a debate over the soul of the Republican Party," said Sen. Josh Hawley, R-Missouri. "Are we going to be a working class party or not?"

"The different ways in which this bill bites working families over and over is going to make it a problem for Republicans in the House and the Senate all the way through November of 2026 and beyond," Sen. Elizabeth Warren, D-Massachusetts, told USA TODAY. An analysis of the House bill released last month by the nonpartisan Congressional Budget Office found that the poorest households would lose about $1,600 a year under the legislation, largely because of cuts to Medicaid and food aid. The wealthiest households would gain about $12,000 a year,according to the CBO. The Senate bill has more aggressive cuts than the House. The CBO estimatesthat nearly 12 million people would lose Medicaid under the Senate bill, with the program facing roughly $1 trillion in cuts. More than250 people protestedthe deep cuts across from the Capitol at the steps of the Supreme Court on June 30, surrounded by dozens of caskets covered with statistics of how many people would lose Medicaid and food assistance in each state. The crowd chanted "you will not kill us and our people without a fight." Warren said criticism of the bill is resonating not just in blue states, but also red states, pointing to polling showing it's broadly unpopular. She recently drew 1,500 people to atown hall in Tennesseeblasting the legislation. "When people know anything about the Republican tax bill they hate it," she told USA TODAY. Republican lawmakers have largely rallied around Trump, accusing Democrats of misrepresenting the legislation. Sen. John Cornyn, R-Texas, said individual elements of the bill poll well but conceded the GOP has some "work to do" to sell the legislation. Trump ran a populist campaign that targeted blue collar voters with proposals such as tax cuts on tips and overtime, and Republicans have pointed to those provisions in the bill to counter criticism that it benefits the wealthy. But some Republican lawmakers worry cutting Medicaid could undermine GOP inroads to the working class. "You cannot be a working-class party if you are taking away healthcare for working class people," Hawley said over the weekend. Yet Hawley still supported the legislation, a sign of how intense the pressure is to deliver for Trump, who also is facing resistance from fiscal conservatives over projections the bill will increase the federal budget deficit by $3.3 trillion. Deficit hawks in the Senate ultimately caved and voted for the bill, and now attention turns to the House, where critics of the legislation's fiscal impact are being egged on by billionaire Elon Musk. "It is obvious with the insane spending of this bill, which increases the debt ceiling by a record FIVE TRILLION DOLLARS that we live in a one-party country – the PORKY PIG PARTY!!"Musk wrote in a June 30 post on X. "Time for a new political party that actually cares about the people." Muskthreated primary challengesagainst GOP lawmakers who support the bill. Trump, meanwhile, is urging his party to fall in line and lashing out at dissenters such as Tillis and Rep. Thomas Massie, who voted against the legislation in the House. In the process, some lawmakers are bowing out. In addition to Tillis,Rep. Don Bacon, a moderate Nebraska Republican who has criticized Trump's megabill, announced he won't seek reelection. Losing lawmakers with bipartisan appeal could make it harder for the GOP to maintain their majorities. The North Carolina Senate race already was a toss up before Tillis resigned, noted University of Virginia political science professor Larry Sabato. It's even more competitive now, he said in a social media post. "Dems should send Trump a fruit basket of thanks,"Sabato said.
