Hill.TV poll: Republicans divided over abortion

Republicans are divided on the issue of abortion, according to a new American Barometer poll, conducted by Hill.TV and the HarrisX polling company.

Twenty percent of GOP respondents said the procedure should be illegal under all circumstances, while 51 percent said it should be legal in limited cases, such as rape, incest and when the life of the mother is threatened. 

Another 20 percent of Republicans said it should be legal up until the third trimester, and only 9 percent said it should be legal under all circumstances. 

The official GOP platform calls for Roe v. Wade, which legalized abortion, to be overturned, and few Republican election officials support abortion rights in all cases.

"Republicans, traditionally the more conservative on this issue, are evenly split on whether it should be law. I read that as for many voters, this is territory that cannot be overturned," Morning Consult senior reporter Joanna Piacenza told Hill.TV's Joe Concha on "What America's Thinking." 

Democrats are also somewhat divided on the issue, with 12 percent saying abortion should be illegal under all circumstances, while 32 percent said it should be legal in limited circumstances, such as rape, incest, and life of the mother. 

Thirty-one percent said it should be legal up until the third trimester, while 25 percent said it should always be legal. 

The American Barometer was conducted on August 31 to September 1 among 1,000 registered voters. The sampling margin of error was plus or minus 3.1 percent.
