"There also are educational differences in awareness of which issue Roe v. Wade addressed. Fully 91% of those with post-graduate education know it dealt with abortion, as do 79% of college graduates, 63% of those with only some college experience and 47% of those with no more than a high school education. Identical percentages of women and men (62% each) are aware that Roe dealt with abortion. Nearly seven-in-ten Republicans (68%) answered this question correctly, compared with 63% of independents and 57% of Democrats."
