Recall that the House missed overriding the President's veto of the original legislation by a mere 13 votes; so, sponsors only need to pick up a few more votes to get a veto-proof majority.
The administration is grumbling, with no apparent sense of irony, that the House is not negotiating. The Hill reports that Secretary of Health and Human Services Leavitt acknowledged that some of the changes addressed administration concerns but said "it would be clear that they are not interested in compromise, that they’re not interested in a negotiation, that they’re simply interested in being able to expand [government] health insurance to higher and higher incomes, that they’re interested in moving people off of private insurance to government insurance, that they’re interested in seeing adults on SCHIP, and so forth."
The SCHIP train may finally be leaving the station. The administration should declare this a return on success and climb on board.
