Here are two recent tidbits that touch on how Harriett Miers might approach Roe v. Wade. First, from the Saturday Washington Post:

  [As a candidate for Dallas City Coucil in 1989,] Miers agreed to sit down with a group of abortion rights activists. Operation Rescue was staging regular protests at area abortion clinics, and the group of about 10 women who met with Miers wanted to know whether she supported a 1985 city ordinance that protected patients from harassment. Four of the women in attendance said in interviews that Miers was immovable.
  "She said, well, I'm sorry, it's murder, and that's that," said Joy Mankoff, founder of a local women's political action network. "There was no room for any discussion."

  And second, from the latest issue of Time Magazine:

  One of the most intriguing insights into the Real Harriet Miers came from her longtime friend, former law partner and sometime love interest Justice Nathan Hecht, who is considered the most conservative justice on the Texas Supreme Court. "This is very important, and I don't think the public understands," he told TIME. "When you take an oath and swear that you will judge cases properly after that, you can't inject your personal views or religious faith into decisions because it would be wrong. You would either be a bad Christian or a bad judge. Religion says a lot about who you are personally, but it says nothing about stare decisis [following precedent], the commerce clause, the First Amendment, search and seizure or any of the issues she's going to deal with."

  UPDATE: For the sake of completeness, I should probably add this article from the Monday New York Times:

  Mr. Dobson, the influential founder of the conservative evangelical group Focus on the Family, has said he is supporting Ms. Miers's nomination in part because of something he has been told but cannot divulge. He has not disclosed the source of the information, but he has acknowledged speaking with Karl Rove, President Bush's top political adviser, about the president's pick before it was announced.
  On his radio program last Wednesday, Mr. [James] Dobson said, "When you know some of the things that I know - that I probably shouldn't know - you will understand why I have said, with fear and trepidation, that I believe Harriet Miers will be a good justice." He added, in a reference to aborted fetuses, "if I have made a mistake here, I will never forget the blood of those babies that will die will be on my hands to some degree."
