The poll, released Monday, showed the same percentage support establishment of a 24-hour waiting period for a woman seeking an abortion. Gallup said nearly two-thirds of those polled favor making a procedure known as "partial birth abortion" illegal. The poll also said 57 percent of Americans oppose laws prohibiting health clinics that perform abortions from receiving federal funding.
The poll found U.S. citizens mixed in their reaction to "conscience laws" that would require women considering an abortion to see an ultrasound image of her fetus.
Gallup said most Democrats and Republicans favor informed consent, parental consent, 24-hour waiting periods and a ban on "partial birth abortion."
Gallup's poll information is based on telephone interviews with 1,020 adults July 15-17. The margin of error is plus or minus 4 percentage points.
