Maybe I Don't Understand Politics At All

The Republicans control both houses of Congress. They have a president that is twice elected. The electorate is composed of a majority of conservatives. So, call me naive, but why doesn't Bush simply throw down the gauntlet: Nominate a person to the Supreme Court that will say he/she is conservative, is a strict constructionist and, without any qualification, say that Roe v. Wade was wrongly decided and, if presented with the same facts, would overturn the decision. The Republicans will not always be in power. Minorities are generally Democrats and, as the years pass, the minority population will dwarf white, conservative, and Republican America. Why doesn't W take charge while he has an opportunity?
