Wikipedia has all the details, but here's the summary:

Roe v. Wade, 410 U.S. 113 (1973), is a landmark decision by the United States Supreme Court on the issue of abortion. Decided simultaneously with a companion case, Doe v. Bolton, the Court ruled 7–2 that a right to privacy under the due process clause of the 14th Amendment extended to a woman's decision to have an abortion, but that right must be balanced against the state's two legitimate interests in regulating abortions: protecting prenatal life and protecting women's health. Arguing that these state interests became stronger over the course of a pregnancy, the Court resolved this balancing test by tying state regulation of abortion to the trimester of pregnancy.

The Court later rejected Roe's trimester framework, while affirming Roe's central holding that a person has a right to abortion until viability.[1] The Roe decision defined "viable" as being "potentially able to live outside the mother's womb, albeit with artificial aid", adding that viability "is usually placed at about seven months (28 weeks) but may occur earlier, even at 24 weeks."[2]

In disallowing many state and federal restrictions on abortion in the United States,[3][4] Roe v. Wade prompted a national debate that continues today about issues including whether, and to what extent, abortion should be legal, who should decide the legality of abortion, what methods the Supreme Court should use in constitutional adjudication, and what the role should be of religious and moral views in the political sphere. Roe v. Wade reshaped national politics, dividing much of the United States into pro-choice and pro-life camps, while activating grassroots movements on both sides.

Problem with this is not the TEa Party, but those behind it. Dick Armey, who claims to be one of the original Tea Party leaders, is tied to jack Abramhoff, a casino magnate who wants his own industry deregulated despite the societal havoc compulsive gambling causes.

And the Koch bros, financiers of many a Tea Party candidate, are part of the problem caused by multi-nationals that have no loyalty to any country.

I don't see any political movement that, from it's leaders on down, has a truly altruistic outlook on the needs of our society. '

I believe that a heartbeat indicates a living human and to kill that heartbeat is murder, and to do it deliberately is premeditated murder. I believe that "partial birth" abortion is as totally gross and cruel as any heinous murder one can imagine. More so because the baby is totally defenseless, but it can feel the pain of being ripped apart. It takes monsters, people without souls, to commit these murders.

For the sake of getting votes, the people who write our laws have sold their souls and are complicit in the heinous murder of millions of Americans via the abortion on demand, when the simple answer is to teach women how to say "no" and to keep their pants on until they are ready to accept a possible pregnancy. If they cannot do that, they can practice birth control in ways that do not result in cruel murder.
