"From 1998 until this year, the U.S. adult public’s support for Roe v. Wade had been declining. A year ago, The Harris Poll reported that Roe v. Wade was supported "only by a slender 49 percent to 47 percent plurality" – "support and opposition are almost equal". Today, a majority now supports the U.S. Supreme Court decision (56% vs. 40%) and almost seven in ten think that the U.S. Supreme Court decision will remain unchanged. What might explain such a shift in 18 months?"
