On the constitutional argument for abortion

I disagree with the US Supreme Court that the Constitution makes no provision for the unborn. It's right there in the preamble:

We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defence, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our *POSTERITY*, do ordain and establish this Constitution for the United States of America.

In fact, I argue that Doe vs Bolton (1973) was such a bad decision that it invalidated the entire constitution and changed the United States from being a philosophically legitimate government to a philosophically illegitimate government. Without the right to life, with the divorce of the Declaration of Independence from the Constitution in Doe vs Bolton (1973), we lost the moral upper hand for the entire country and the entire basis of law.
