President Bush and his likely Democratic rival John Kerry hold markedly different stands on the issue of abortion, with Mr. Bush saying he opposes the practice while Mr. Kerry says he supports a woman's right to choose.
President Bush has said he believes efforts to overturn the landmark 1973 Supreme Court decision that legalized abortion - Roe versus Wade - are a "noble cause."
And since last year, Mr. Bush has signed two pieces of legislation sought by anti-abortion activists. These include a ban on a procedure referred to as partial birth abortions and a federal law that gives a fetus or embryo legal rights separate from the mother.
Mr. Kerry says he firmly backs the Roe-versus-Wade court decision and a woman's right to choose whether or not to have an abortion. He says a woman's right to control her body is constitutionally protected.
Mr. Kerry says if elected, he will only support pro-choice judges to the Supreme Court. He also adds that he believes the rights of women are at risk under the Bush administration.
