The Democratic-run Senate is poised to vote down a controversial House budget plan that calls for turning Medicare into a voucher-like program for future beneficiaries.

In a prelude to a summer showdown with President Barack Obama, Republicans controlling the House pushed to passage on Friday a bold but politically dangerous budget blueprint to slash social safety net programs like food stamps and Medicaid and fundamentally restructure Medicare health care for the elderly.

The House has passed a Republican budget blueprint proposing to fundamentally overhaul Medicare for future beneficiaries while combating out-of-control budget deficits. It would impose sharp spending cuts on social safety net programs like food stamps and Medicaid.

A bold but politically risky plan to cut trillions of dollars from the federal budget steamed toward a party-line House vote Friday, as insurgent Republicans rallied behind the idea of fundamentally reshaping the government's role in health care for the elderly and the poor.

The House, in a bipartisan vote, has passed a yearlong government funding measure cutting $38 billion from the budget and closing out sometimes quarrelsome negotiations between the Obama administration and Republicans dominating the House.

The House and Senate are ready to vote on legislation cutting almost $40 billion from the budget for the current year, but President Barack Obama and his GOP rivals are both eager to move on to multi-year fiscal plans that cut trillions instead of billions.

It's touted as the biggest one-time rollback of domestic spending ever, but most folks will be hard-pressed to notice. After all, it's just 1 percent of what the government will lay out this year.
