They bow to capitalism so an American president will never be left just like you say.But Obama, Biden or Trump is the same shit, all right wing politicians. What they do or don't do in relation to cannabis honestly doesn't matter from the point of view of economic polarities, it's not what makes them left or right, you know? Left and right go far beyond that, it's how the means of production are organized, that doesn't change because of an electoral and populist measure, whether someone wears colored hair or not is just a trick to fool voters. The day an American president talks about agrarian reform, the overthrow of large estates, the taking of large fortunes and properties for the people, the day an American president defends the end of slavery committed by large companies, better wages and shorter working hours, then you can perhaps call one of them a "leftist".
