Can a state make federal offenses state offenses as well, so that even if the president pardons a criminal for a federal offense, they'll still be on the hook for the equivalent state offense?
Edit:
It appears they can't do this for every offense (since some might be "occupying the field", etc.), but can they even take this route for a reasonably large number of offenses? Is there any precedent for such a thing or other reason to believe that if there was "space" for such legislation, and the intention was clear, it would be upheld?
(Not actually sure if this belongs under Law or Politics... please migrate as appropriate.)
