...State has the right to legislate on abortion, State has the right to legislate on sports gambling...Effectively, no federal abortion rights were created (the subsequent decision in Planned Parenthood v Casey eliminated the trimester analysis), although a privacy right was recognized as being infringed... there is no federal right, to either have or prohibit abortion in all circumstances, or to sports gamble or prohibit sports gambling in all circumstances...it was left to the States...Most states have legislated legal abortions out of existence without running afoul of Roe v Wade. All the Court did was give the States a roadmap for regulation...
Your claim that "...Most states have legislated legal abortions out of existence..." is ridiculous. There are a number of states that would
like to outlaw abortion but they cannot do so because the SCOTUS has decided that a woman has
a fundamental constitutional right to abortion under the implied right to privacy supposedly found in the 14th Amendment (though the word "privacy" is nowhere in the Constitution). Any state that has tried or would try to outlaw abortion has had or would have the law easily overturned by the SCOTUS.
The fact that 10th Amendment allows states to
regulate abortions is of secondary importance. They can
regulate but they cannot
ban.
On the other hand the SCOTUS decision on gambling did not rule that there is a fundamental constitutional right to bet on sports. It just said that it is a question for the states to decide one way or another-legalize or ban it.
A state cannot ban abortion but it can ban sports gambling.
If the Court had based the abortion decision on the 10th Amendment, then it would have maintained the status quo at the time, i.e. that abortion is a question for the states to decide and the Constitution has nothing to say about it. Abortion was already legal in NY when Roe v. Wad was decided. It probably would have eventually been legalized (and regulated) in many other (but not all) states.
If the gambling decision were similar to the abortion decision as you suggest, the SCOTUS would have ruled that states cannot ban sports gambling (just like they can't ban abortion) but they can just regulate it. It would be fun to have the SCOTUS rule that there is a fundamental constitutional right to gamble on sports...and smoke weed and pay for sex. Maybe we'll see that someday. :lol:
These are two different decisions based on different parts of the Constitution.
