The Dobbs (abortion) case: The US Supreme Court decision is constitutionally sound. The Court has jurisdiction over the unconstitutional Court decision in Roe v. Wade and finally overturned it. Roe v. Wade was unconstitutional because 1) the feds have no constitutional authority regarding abortions and 2) the feds have no jurisdiction over state abortion laws.
The Bruen (gun) case: The US Supreme Court decision is constitutionally unsound because the Court has no jurisdiction over NY State gun laws. This appears to be a victory for our Free Constitutional Republic, but it in not because it strengthens more unconstitutional federal power over the states. The greatest threat to our lives and wellbeing is the unconstitutionally unlimited and totalitarian power of the federal government.
The principle of Incorporation from the 14th Amendment says the Bruen decision is sound. States can’t have laws that contradict the Constitution.
