You do know she fought against the Bar trying to take a pro-choice stance?
I've been trying to get some details on that, such as one of the letters that she sent from the Texas Bar to the ABA. Seems the pro-choice resolution had some history to it, not "passing" the first time it was proposed. Oh, I haven't found the resolution either.
THE FEMINIST CHRONICLES - 1990The resolution was adopted in 1992, and again was objected to by the Texas Bar.The American Bar Association (ABA) rescinded the policy it adopted in February opposing legislation that interfered with a woman's constitutional right to terminate a pregnancy at any time before viability or thereafter to protect her life or health. The ABA adopted a policy that it characterized as "neutral," taking no position on abortion. (08/90)

Travis County Women Lawyers' Association (TCWLA) announced publicly in March 1990 its support of the right of women to make their own reproductive choices. This announcement was a direct response to a letter by the president of the State Bar of Texas to the American Bar Association (ABA) denouncing the ABA's adoption of a pro-choice resolution.
But, in any event, I think Miers' participation is as the person who represents the interests of the Texas bar, and her actions as such don't necessarily reflect her personal point of view. Quite a few ABA memvbers resigned from the ABA when the resolution was passed. Miers did not resign.
