The problem with the poll is that "Available under stricter limits" could easily be interpreted as meaning illegal except in cases of "rape, incest, and to save the life of the mother".
I would not call someone favor those restrictions as pro-choice.
The problem with your poll is that "pro-choice" isn't any more precise or accurate than the aggregate of polls I showed.
CNN/ORC Poll. Aug. 22-23, 2012. N=1,055 adults nationwide. Margin of error ± 3.
"Do you think abortion should be legal under any circumstances, legal only under certain circumstances, or illegal in all circumstances?"
Always legal - 35%
Sometimes legal - 47%
Always illegal - 15%
82% think it shouldn't always be illegal. Some of them will identify as pro-choice, some won't. Some think it should be illegal only in cases of rape or to save the life of the mother. Some think it should always be legal except to determine gender or other physical traits.
Some who are in the "sometimes legal" category will identify as pro-choice, too.
You Ryan who according to Democrats wanted to ban abortions in all cases helped Romney's appeal with women?
Since when do you buy what Democrats said about Ryan?
