"Capping months of months of struggle, House Democrats cleared an abortion-related impasse blocking a vote on sweeping health care legislation late Friday and officials expressed optimism they had finally lined up the support needed to pass President Barack Obama’s top domestic priority. ... Under the arrangement, Reps. Bart Stupak of Michigan, Brad Ellsworth of Indiana and other abortion opponents were promised an opportunity to insert tougher restrictions into the legislation during debate on the House floor. The leadership’s hope is that no matter how that vote turns out, Democrats on both sides of the abortion divide will then unite to give the health care bill a majority over unanimous Republican opposition."
