You might call it the last running of the old bulls in Congress.
In the waning days of, Democrats controlling the Senate - in collaboration with a handful of old school Republicans - are pushing to wrap more than $1.2 trillion worth of unfinished budget work into a single "omnibus" appropriations bill.
Their 1,900-plus-page bill comes to the floor this week stuffed with provisions sought by lawmakers. It contains thousands of pet projects, known as earmarks, pushed by Democratic and GOP senators alike -to give up such projects next year.
"That omnibus bill will be loaded down with earmarks and pork barrel spending, which is a direct - a direct - betrayal of the majority of voters on Nov. 2 who said 'Stop the earmarking, stop the spending, stop the pork barrel projects,"' protested Sen. John McCain, R-Ariz.
The catchall bill is designed to bankroll the operations of every Cabinet agency for the budget year that started Oct. 1, as well as provide more than $100 billion to pay for wars in Afghanistan and Iraq.
It also challenges President Barack Obama. One administration-opposed provision would block the Pentagon from transferring Guantanamo Bay prisoners to the United States. Another would continue a program to develop a second engine for the F-35 Joint Strike Fighter despite a veto threat by the administration, which says it's a waste of money.
The architect of the measure, Senate Appropriations Committee Chairman Daniel Inouye, D-Hawaii, has been working with senior Republicans on the panel - Thad Cochran of Mississippi, Robert Bennett of Utah and Christopher Bond of Missouri - to line up the 60 votes needed to repel a filibuster promised by GOP Sen. Jim DeMint of South Carolina and other conservatives.
"We remain cautiously optimistic," said Inouye spokesman Rob Blumenthal.
Inouye's measure would replace a slightly less expensive bill that the House passed last week. The House bill doesn't contain earmarks like road and agricultural research projects, water treatment plants and grants for local anti-drug campaigns.
House Democrats, however, would gladly accept the fatter Senate version. Its many earmarks include $80 million in grants to states and Indian tribes to preserve Pacific salmon and $13 million in clean water grants for rural and Alaska native villages.
The year-end logjam continues a long tradition in which a dysfunctional Congress is unable to do its most basic job of providing money to run the government on time.
Rather than debating a dozen separate appropriations bills, the omnibus spending measure rolls all the spending bills into a single piece of legislation that is likely to be brought to the floor in a way that keeps opponents from trimming it down.
Democrats hope to pass the measure by a midnight deadline Saturday. That would give them the latest - and perhaps last - victory over conservatives who contend the annual appropriations bills spend too much money and contain too many pork-barrel projects.
Incoming House Speaker John Boehner, R-Ohio, is a long-standing opponent of doling out federal dollars for sewer projects, community development grants and the like based on special requests from lawmakers.
Boehner will become the single most powerful member of Congress next year, and he has laid down the law,. He signed a letter last week asking Obama to veto the omnibus bill because of its earmarks.
For now, though, Boehner still is outnumbered by Democrats.
And across the Capitol, Democrats control the Senate with 58 votes. But their numbers will shrink to 53 in January, and many of the 13 incoming Senate Republicans are replacing eager earmarkers like Bond and Bennett, who follow the rich Appropriations Committee tradition of banding together, regardless of party, to beat back critics of their spending.
While Senate Minority Leader Mitch McConnell, R-Ky., has come out against the omnibus measure, he hasn't been pressing hard to block it.
But GOP conservatives are irate over provisions that would begin to pay for Obama's overhauls of the U.S. health care system and financial services regulations.
