Of course it is. Liberals want to exercise "states" rights only when it suits THEIR goals.
The 9th and 10th are there for a reason - not just to be window dressing.
It's hilarious. the same people who claim there's no such thing as reserved state powers when they want to make suffrage universal, now want to try to use a doctrine they don't understand and have rejected. They'll screw it up royally because they have no understanding of the principle of federalism or of reserved state powers.
It will be like watching a three year old play with Daddy's chain saw.
