Yes....he did..
As president, he would have the power to direct agencies to essentially leave it alone federally. But Ted’s a bit different then Obama.
In the case of laws enacted by congress, should there be one or two that might interfere with the States in this narrow topic of Marijuana, I don’t believe that Ted would do it in the way Obama has by ignoring Fed law. Ted would use his legitimate powers but not usurp the powers of Congress.
If necessary, the way this is supposed to work is that the Executive branch would work with congress to get a minor revision done on the language.
