here is the most important part of the survey
Gallup's longest-running measure of abortion views, established in 1975, asks Americans if abortion should be legal in all circumstances, legal only under certain circumstances, or illegal in all circumstances. Since 2001, at least half of Americans have consistently chosen the middle position, saying abortion should be legal under certain circumstances, and the 52% saying this today is similar to the 50% in May 2011. The 25% currently wanting abortion to be legal in all cases and the 20% in favor of making it illegal in all cases are also similar to last year's findings.
