I think most people would lean towards AOC since there seems to be lack of competition in the area of charisma and not-being-old categories.
Who do you think could be the next “Bernie Sanders” that could possibly run for president in 2028/2032? A lot can happen over the next 4 years, so 2028 there could still be a chance for a progressive president.
It’s a little bit hard to say, as - like you say - the political landscape can fundamentally shift in four years.
That said, I am very much hoping that a labor-derived leader might stand up in the next few years. I’m not aware of one just yet, but that is where I’d look, particularly as automation and concentration of wealth become steadily greater problems.
