While I agree that the common populace of the US has mostly reached an understanding that marijuana prohibition has far higher costs compared to gains (and was initiated for extremely unjust reasons) - we aren't there yet. National legalization is unlikely to happen regardless of who takes the Senate+House+Presidency in the coming term with a possibility of it happening if a lot of pressure is applied on the Democrat side (and assuming they hold significant political power).

The fight isn't over. While the populace has coalesced the political will is still lagging behind.
