WASHINGTON (AP) — Senate Democrats and House Republicans are pushing rival plans to reduce future budget deficits and avert a potential government default next week. Neither plan raises taxes or cuts major benefit programs such as Medicare, Medicaid or Social Security.

___

The plan by Senate Democrats would cut spending by $2.7 trillion over the next decade, while increasing the government's ability to borrow by $2.4 trillion.

— Extends borrowing authority through 2012.

— Cuts $1.2 trillion from discretionary programs. These are the day-to-day operating budgets, grants and programs of government agencies, such as the Interior, Education Justice and Defense departments and the Environmental Protection Agency.

— Claims savings of $1 trillion from winding down the wars in Iraq and Afghanistan.

— Saves $400 billion from lower interest payments.

— Cuts $100 billion from mandatory programs, including agriculture, Fannie Mae and Freddie Mac. Includes savings from reducing waste, fraud and abuse.

— Creates a bipartisan legislative committee to recommend future cuts, with a guarantee that if the panel can agree on a plan, it will receive a vote in Congress.

___

The plan by House Republicans would reduce spending by $1.2 trillion over 10 years, while increasing the government's ability to borrow by about $1 trillion.

— Extends borrowing authority until about February.

— All cuts would come from the day-to-day operating budgets of government agencies, known as discretionary programs.

— Imposes caps on future spending.

— Requires the House and Senate to vote on — but not necessarily pass — a balanced budget constitutional amendment by the end of 2011.

— Creates a bipartisan legislative committee to recommend $1.8 trillion in future cuts to programs such as Medicare, Medicaid and Social Security, in exchange for increasing the government's ability to borrow an additional $1.6 trillion.
