A majority of Americans say the Supreme Court should uphold Roe v. Wade, the landmark ruling that established a constitutional right to abortion, Washington Post-ABC News poll conducted last week finds.

With the Supreme Court poised to overturn the right to abortion, the survey finds that 54 percent of Americans think the 1973 Roe decision should be upheld while 28 percent believe it should be overturned — a roughly 2-to-1 margin.

The Supreme Court is consideringa Mississippi law that would ban abortion after 15 weeks. Such a restriction seemed forbidden by Roe and a subsequent decision that said states could not place undue burden on the right to abortion before fetal viability, usually seen as 22 to 24 weeks. The Supreme Court is preparingto overturn Roe in this case, according to a leaked draft of the opinion published Monday by Politico.
