Sen.

He is the first Democrat to sponsor such a measure in many years.

Udall is introducing his balanced budget amendment bill with Sen. Richard Shelby (R-Ala.). The bill would require that spending not exceed revenue in any given year.

Udall’s move is being taken as a sign of the unusual momentum deficit hawks enjoy in this Congress compared to previous years. It comes on a day when the Democratic head of the Senate Appropriations Committee, long-time earmarker Sen. Daniel Inouye (D-Hawaii), announced a two-year ban on earmarks in his committee. Udall had pushed for such a ban in the last Congress.

The Udall bill would also limit federal spending to the historical average of 20 percent of gross domestic product in a given year. It currently stands at 24.7 percent.

The Udall bill would allow Congress, through three-fifths votes in both houses, to waive the balanced budget requirement.

A balanced budget amendment would require support from two-thirds of both Houses and three-fourths of the states in order to become part of the Constitution. In 1997, a balanced budget amendment with bipartisan support and fell just shy of the votes needed for passage.

“This amendment would send a strong signal to the financial markets, U.S. businesses, and the American people that we are serious about stabilizing our economy for the long-term,” Udall said in a statement.
