The difference between the U.S. House and U.S. Senate debate on the Stupak amendment is stark.
The pro-abortion Members of Congress in the House, and pro-abortion groups like NARAL and Planned Parenthood, rolled over and did not threaten to derail the bill because Speaker Pelosi asked them to. So they played dead.
Senator McCaskill (D-MO), who is pro-abortion, publicly said she could live with the Stupak amendment. (This link also shows the deep net-roots anger against NARAL and Emily's List for playing dead and letting Stupak pass at the request of the Speaker.)
Senator McCaskill is not the Speaker of the House, and she was not so lucky — she did not get a free pass.
She was instantly pounded by pro-abortion forces. Senator McCaskill has now changed her tune — she will not support Stupak in the Senate — all in the same day.
Pro-Abortion Forces on the Defensive
The precedent set by the Stupak amendment in the House has put the pro-abortion forces on the defensive. They lost a major battle and are now reacting very aggressively.
They cannot allow a Stupak type amendment to pass the Senate. It will make their position in Conference extremely weak, untenably weak. It will lock-in the pro-life victory in the House.
If the Senate also passes an amendment, close to or like the Stupak amendment, then the bill coming out of Conference would force the pro-abortion groups to oppose the Conference report, and they would have to join with the Republicans to kill ObamaCare.
