Republicans find few alternatives to Trump’s budget plan.

WASHINGTON — Congressional Republicans greeted President Donald Trump’s first full budget on Tuesday with open hesitation or outright hostility. But it was not clear that they could come up with an alternative that could win over conservatives and moderates while clearing a path for the tax cuts and policies they have promised for years.

The budget battle ahead mirrors the continuing health care fight, in which concessions to Republican moderates alienate conservatives, while overtures to conservatives lose moderate votes. But with Republicans in full charge of the government, the onus is on their leaders to reach a budget agreement in a matter of weeks that would ease passage of the president’s promised tax cuts as well as a new spending plan that would reshape the government in a Republican mold.

“It is now up to the Congress to act,” Trump said in his budget message. “I pledge my full cooperation in ending the economic malaise that has, for too long, crippled the dreams of our people. The time for small thinking is over.”

Trump’s $4.1 trillion budget, with its deep cuts to poverty programs, biomedical research, student loans and foreign aid, will not pass, as Republicans on Capitol Hill have freely acknowledged and even the White House is aware. Republicans on Capitol Hill parted ways with the president not only on many of his deepest cuts but also on some of his smaller proposals, like resurrecting a national nuclear waste repository in Nevada and ending the Great Lakes cleanup program.

Rep. Harold Rogers, R-Ky. and a former chairman of the House Appropriations Committee, called the cuts “very harmful.” Sen. Dean Heller of Nevada, perhaps the most endangered Senate Republican up for re-election next year, labeled the budget “anti-Nevada.”

But the drastic reordering of government that Trump has embraced includes many measures long sought by conservatives on Capitol Hill, including adding work requirements for foodstamp eligibility and opening the Arctic National Wildlife Refuge to oil drilling. It also would eliminate whole programs, including AmeriCorps, the Corporation for Public Broadcasting, the National Endowment for the Arts and the Low Income Home Energy Assistance Program.

The budget would increase military spending by 10 percent and calls for spending $2.6 billion on border security, including $1.6 billion to begin funding a wall on the border with Mexico.

Some of the president’s proposals are likely to survive.

Trump’s budget, drafted by a budget director, Mick Mulvaney, who came from the most conservative corners of the House, starts the conversation on friendly House Republican turf.

Republican lawmakers already face a time crunch, given that Trump offered his budget three months past the statutory deadline in February.

While new presidents routinely take more time to submit their inaugural budgets, Trump unveiled his unusually late, and in an uncommonly low-key fashion, dispatching his budget director to unveil the plan while he was overseas. That raised questions about whether he would take a leadership role in the coming spending debates.
