Conflicts Between US and State Constitutions

Well, over in GD, there is a thread on guns. In it, I posted

Now, am I anywhere close to right? As I understand it, the states cannot give less protection than the fed does, but they can give more. So, just because an amendment in the US constitution is annulled, it does not mean that the State constitutions do not hold, at least at the state’s jurisdicitional level or below, correct? So, what if another version of the 18th amendment (prohibition) is passed, but in this case is a combination of annulling the 2nd amendment and banning all private gun ownership in the United States? Would this completely annul all State constitutions, or would we be looking at a jurisdictional and court battle that, in my opinion, would make the current fight over marijuana laws insignificant? Has there been any discussion or thought of the matter by Constitutional scholars?

If the second amendment were annulled, the various state constitutions that contain some sort of protection for gun ownership would still apply.

If a constitutional amendment banning gun ownership were to pass, then the state constitutions would be superseded by the new amendment.

In fact, if the second amendment were annulled and a federal statute banning guns were to pass, that would also supersede the state constitutional provisions.

You’ve got it backwards. The state constitution can do less but it can’t do more.

I’m not a lawyer but I’m not sure that a federal law banning firearms within a state would be constitutional.

The powers of Congress are:

The Congress could, I guess, prohibit shipment of weapons in interstate commerce. Maybe the the powers could be stretched so it would be ruled “necessary and proper” to pass a federal law banning guns everywhere to “provide for the common devense and general welfare.”

I don’t see anything else in the powers of Congress that would cover such a law.

If a state constitution grants less rights than the federal does, then the citizen of this state can derive their right directly from the federal constitutíon, because it applies to every US citizen no matter which state they’re in; if a state constitution grants more rights than the federal does, then the state citizens can derive those rights from their state constitution without having to resort to the federal one. In effect this does mean that no US citizen can have less rights than provided for in the federal constitution, but they can have more if provided so in the particular state constitution.
Of course this does not apply if federal laws explicitly ban something; the state laws or constitutions cannot allow something that’s prohibited by applicable federal laws. Problem is that the feds need jurisdiction over that particular matter, or else the federal lw would be unconstitutional.

[minor nitpick]
According to the beliefs of our Founding Fathers, a constitution cannot grant or give rights. It can only promise to ***protect *** rights the people were born with.
