LEGISLATIVE CHICANERYBad news - a judge just denied Metcalf's motion to dismissed based on unconstitutionality of the act. https://casetext.com/case/united-states-v-metcalf-35
3) Why hasn't anyone successfully challenged all federal firearms laws based on the fact there is no delegated power to regulate firearms and no "police powers" delegated to the federal government within the Constitution.
Because all laws passed by the legislature are presumed to be constitutional based on the silly notion that lawmakers will honor their oaths of office.
While it may be that there could be legitimate opinion differences in some phraseology in the Constitution, still, they can vote for something that is plainly contrary to the plain English language of our founding document and lie to themselves that they think the law they are voting for is "constitutional."
They also fool themselves into thinking they can get away with it based on the "no right is absolute" thesis. While this may be technically true (e.g., incarceration, capital punishment), application of this concept can be unlimited. That is, to put it simply, since "no right is absolute," we can "reasonably" tinker with it all we care to... without any limit.
And remember, no matter how blatantly unconstitutional a law may be, it takes a lot of money and time to have it actually declared, legally, unconstitutional, by SCOTUS.
The legislators rely on that. Too friggin' much.
That's why.
