82% of Americans favor some form of legal abortion. 17% are opposed to all abortion.
The numbers have been essentially the same for 20 years.
Nice try at distorting the facts. By the same survey you chose to quote from, 73% of respondents feel that abortion should be illegal in some cases. This survey asked about abortion in the positive sense, so it is likely that the pro-abortion count reflected by it is exaggerated. Most neutrally oriented surveys show a slight plurality on pro-life side.
The country is very evenly split on this issue, regardless of how the pro-abortion crowd attempts to spin it.
