That certainly reduced the polls to meaninglessness, with "all" and "most",

48% of Americans call themselves "pro-life" and 45% "pro-choice". (Gallup)

Americans who profess no religious identity are  heavily pro-choice, at 80%, followed by liberals and Democrats, among whom pro-choicers outnumber pro-lifers by at least 2-1.

The strongest pro-life skew is among Republicans and conservatives, of whom about two-thirds are pro-life. Slight majorities of Catholics, Protestants, non-whites, Southerners, and seniors are also pro-life.

But when SPECIFIC procedures are posed to those polled, even a majority of "pro-choice" Americans favor banning certain procedures, banning certain reasons for abortion, and banning abortions outright after a certain point in the pregnancy, which belies the "64%-32%" black and white fiction.
