Rep. Bart Stupak (D-MI) To Retire

After weeks of attacks from both the right and the left over his changing position on health care reform, Rep. Bart Stupak (D-MI) has decided not to seek reelection.

Stupak negotiated with Democratic leaders down to the eleventh hour for stricter abortion language in the health care bill, but he ultimately voted for it after President Obama agreed to sign an executive order assuring the new laws will keep taxpayer dollars from funding abortions. That prompted the conservative Tea Party Express to launch a $250,000 ad campaign against Stupak this week. The group also scheduled a handful of stops on its bus tour in Stupak's district. On the left, the abortion rights group NARAL Pro-Choice America has been working to defeat Stupak and instead elect his Democratic primary challenger Connie Saltonstall. Like many other congressmen, Stupak received violent threats from citizens after his health care vote. However, the Michigan Democrat came under particularly intense scrutiny because of his role in the abortion debate.
