WASHINGTON (AP) — The Senate moved ahead Tuesday on a compromise Republican budget that calls for future cuts in spending while immediately boosting Pentagon accounts by an additional $38 billion.

The House approved the non-binding blueprint last week, and a final Senate vote on Tuesday afternoon would complete action. First, the chamber voted 53-44 to move forward with the House-Senate compromise.

The measure sets a potential path for a balanced budget within a decade, cuts to domestic programs, and the repeal of President Barack Obama's signature health care law.

Republicans and many economist say balancing the budget helps the economy in the long run and that it's better to tackle the long-term financial problems of programs like Medicare and Medicaid sooner rather than later. They also promise to relieve the burden of debt that's being passed on to future generations.

"That's really unconscionable, to keep spending money and then send the bill to our kids and grandkids and say, 'You pay it. We had a good time. Good luck,'" said Sen. John Cornyn, R-Texas.

The budget plan does not go to Obama, who has promised to veto follow-up spending bills that he says will shortchange domestic programs like student aid, highway construction, and scientific research.

The measure pleases the GOP faithful by setting up a debate this summer that would permit Republicans to finally pass legislation to repeal Obama's health care law. That's because Senate Democrats would be unable to filibuster the repeal bill under fast-track budget rules, though Obama is certain to veto it.

But Republicans have no plans to follow up the budget plan's call for more than $5 trillion in spending cuts with binding legislation that would, for instance, curb Medicare payments to providers, tighten eligibility rules for food stamps, or dump poor and disabled people off of the traditional Medicaid program.

Democrats blasted the measure for getting the bulk of its savings from cuts to programs that help the poor and middle class while leaving defending tax breaks for corporations and the wealthy, including a proposal to eliminate taxes on multi-million-dollar inheritances.

"This is an absolute disaster for the working families of this country," said liberal Independent Bernie Sanders of Vermont, who's running for the Democratic presidential nomination. "In fact, one of the problems that I have had in describing the Republican budget is that it is so bad ... that people don't even really believe you when you talk about what is in this budget."

The budget sets up a battle later this year over the 12 annual spending bills setting agency operating budgets. Republicans have skirted budget rules and are trying to award the Pentagon a 7 percent budget hike while keeping domestic programs frozen at current levels.

Obama and his Democratic allies in the Senate say they will block those budget moves and are calling for a budget summit that would replace immediate and automatic budget cuts known as sequestration with longer-term substitute cuts and revenues from closing tax loopholes. Republican leaders like House Speaker John Boehner of Ohio say tax increases are out of the question.

Under Washington's arcane budget process, lawmakers first adopt a budget that's essentially a visionary document that sets goals that politicians are often unwilling to pursue. The GOP document also lacks specifics about which programs would be cut, insulating the Senate's large crop of vulnerable incumbents from taking a more politically dangerous vote.

The measure manages to chart a path toward balance without new taxes, though it assumes Republicans will find about $1 trillion over 10 years to replace "Obamacare" taxes like the 3.8 percent surcharge on investment income paid by upper-bracket earners. It also retains large Obamacare cuts to health care providers such as Medicare Advantage plans even though Republicans criticized the cuts in past campaigns.

Senate Republicans prevailed in a debate over a Medicare plan championed by House Republicans that would give people joining the system after 2024 a subsidy to purchase health insurance on the open market rather than a guaranteed package of services. That plan has failed to resonate in the Senate, particularly among incumbents up for re-election next year in states carried by Obama.

In order to promise a balanced budget, the GOP plan fails to sustain its promised increases for the Pentagon and relies on unrealistic cuts of an additional $500 billion over 10 years from domestic agencies already slammed by sequestration. Medicare would be cut by more than $400 billion over 10 years, enough to extend its solvency for a few years.
