Pro-life is the name given to people or organizations who defend the rights of the unborn child, and who oppose abortion.
While pro-abortion would be an accurate term for those who profit from abortion and support taxpayer funding of abortion, pro-choice is the term preferred by liberals.
Due to rulings by the U.S. Supreme Court, the United States allows abortions at virtually any time in pregnancy. Many state governments even pay for abortions using taxpayer dollars.
In American politics, the Republican and Constitution Parties are strongly opposed to abortion and believe it should be illegal. The Democratic and Libertarian Parties both support abortion and oppose legal restrictions. The Democratic Party supports taxpayer-funded abortion.
