Two-thirds of voters in today's midterm election favor keeping Roe v. Wade, the landmark 1973 Supreme Court ruling on abortion, as it is, according to early results from the NBC News Exit Poll. About one-quarter of voters say the ruling should be overturned. 

Republicans are closely divided on this question, with 44 percent in favor of keeping Roe v. Wade as is and 45 percent saying it should be overturned. Substantial majorities of both Democrats and independents say Roe v. Wade should be left as is.
