Few people have gone from hero to heavy so quickly in American politics as Rep. Bart Stupak, who billed himself as the champion of the unborn ... until he sold his vote to the abortion industry to support Obamacare.

Columnist Kathleen Parker offers a look at Stupak's pathetic betrayal of the pro-life movement.

From her column:

Ultimately, he was weak and overwhelmed by raw political power. History is no stranger to such moments, but this one needs to be understood for what it was. A deception.

The executive order promising that no federal funds will be used for abortion is utterly useless, and everybody knows it. First, the president can revoke it as quickly as he signs it.

Second, an order cannot confer jurisdiction in the courts or establish any grounds for suing anybody in court, according to a former White House counsel. The order is therefore judicially unenforceable.

Finally, an executive order cannot trump or change a federal statute.

One can reasonably surmise that Obama, a former constitutional law professor, is well aware of the uselessness of his promise. Perhaps this is why he didn't mention it during the bill-signing ceremony Tuesday.

Stupak, too, knew that the executive order was merely political cover for him and his pro-life colleagues. He knew it because several members of the U.S. Conference of Catholic Bishops explained it to him, according to sources. The only way to prevent public funding for abortion was for his amendment to be added to the Senate bill.

Clearly, House Speaker Nancy Pelosi and the president didn't want that. What they did want was the abortion funding that the Senate bill allowed.
