If Trump supported the constitution he would have railed against 50 years of constitutional precedent overturned by an activist right wing court.
Todays republican party seems hell bent on losing a bevy of unenumerated rights because they wish to ignore the 9th amendment.
James Madison put a lot of work to prohibit this type of pseudo legal affirmation.
9th amendment: The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
Madison, in order to salvage a bill of rights and it's addition to the constitution had this to say...
It has been objected also against a bill of rights, that, by enumerating particular exceptions to the grant of power, it would disparage those rights which were not placed in that enumeration; and it might follow by implication, that those rights which were not singled out, were intended to be assigned into the hands of the General Government, and were consequently insecure. This is one of the most plausible arguments I have ever heard against the admission of a bill of rights into this system.7
Justice Story articulated the need for the 9th amendment
.
As Justice Joseph Story explained, the clause was manifestly introduced to prevent any perverse, or ingenious misapplication of the well known maxim, that an affirmation in particular cases implies a negation in all others.
It seems to me today's republicans want to negate the 9th amendment and all states to be able to revoke all the unenumerated rights all in the name of the 10th amendment.
Roe v Wade is gone. Shall we ignore the 9th further and allow states to strip other unenumerated rights? The right to marriage? Presumption of innocence? The right travel?
This is what the right is asking for. Don't let them do it. Don't let your states revoke your rights.
