The Democratic party's liberal wing is trying to force a retreat from a deal struck in the House to ensure that federal funds aren't used for abortions under a healthcare overhaul. The House, in the final stages of debate over its version of health legislation, passed an amendment authored by Michigan Democratic Rep. Bart Stupak that blocked abortions—except in cases of rape, incest or a threat to the life of the mother—from being covered by a government-run health-insurance plan, or by any insurance plans bought with the help of government subsidies. The move has created a divide in the health reform debate, the Wall Street Journal reports.
