On the other hand: Supporters of abortion rights say Obama was right to oppose the 2003 bill, even though it had the same wording as the federal measure. The wording could have had a different effect at the state level, they say, by undermining Illinois' legal precedents on abortion.
Once more, the key is the 1975 Illinois abortion law, which contains language that's similar but not identical to the later bill. The 2003 bill could have affected the way courts interpret the 1975 law, which Planned Parenthood and the Illinois State Medical Society contended could have far-reaching implications.
The groups opposed the entire group of "born alive" bills that were introduced starting in 2001, saying they could ultimately threaten the physician-patient relationship and increase civil liability for doctors.
In 2005, Illinois lawmakers inserted an extra provision asserting that the law would not affect "existing federal or state law regarding abortion." The measure passed without opposition from Planned Parenthood and with the support of groups opposed to abortion.
Footnote: This isn't the first time Obama's record on "born-alive" legislation has raised questions. His opponent in the 2004 U.S. Senate race, Alan Keyes, said Obama's support for "infanticide" was the main reason he came from Maryland to challenge Obama for the seat. Keyes lost to Obama in a landslide.
