You make an excellent point regarding federal drug law as it relates to state-by-state legalization. It's fascinating that here we have a case of the executive blatantly refusing to enforce the law, but Congress also blatantly failing to press the issue (which they could) because they know doing so would be incredibly unpopular... But at the same time, refraining from codifying that policy into law, because doing so would be incredibly unpopular with the percentage of the electorate that still believes marijuana should be illegal.

It's weird to watch.
