GOP adds constitutional amendment to budget fight

Congressional Republicans are rallying behind a long-shot bid for a constitutional amendment requiring a balanced budget. But they're divided over conservatives' efforts to demand its passage as their price for backing any increase in the government's borrowing limit.

Right in the middle of their brawl with President Barack Obama over extending the debt ceiling and hacking trillions from projected deficits, GOP leaders are forcing House and Senate debates next week over similar amendments requiring the budget to be balanced, starting no sooner than five years from now. Reflecting tea party clout, both measures would also sharply curb Congress' ability to raise taxes and spending.
