The Republican leadership in the House had planned on passing a budget bill today, but the likelihood of their success appears to be diminishing, as CQ Today's Midday Update (a free email service) reports.

In a sign of trouble for the Republican leadership, the House recessed this morning shortly after convening, delaying consideration of a $50 billion budget savings bill.

Although GOP leaders last night expressed confidence that they had made enough changes to bring their moderates on board and pass the bill, the delay suggested they still don’t have the votes.

The leadership dropped provisions to allow oil drilling in Alaska’s Arctic National Wildlife Refuge (ANWR) and offshore, and softened planned cuts to food stamps for legal immigrants. They hoped that would suffice to win the last of the Republican votes they will need to pass the budget-cutting package. No Democrats are expected to support the measure.

But leadership may have conceded too much to the moderates, and in doing so lost the votes of some ardent ANWR supporters. Furthermore, as of this morning, changes were under discussion involving the $12 billion package of cuts to Medicaid contained in the bill.

No oil drilling in ANWR. No more tax cuts. Has the unravelling of the GOP coalition in Congress commenced?
