Well she's not tilting her party to the extremes. Fifty years ago everyone agreed with her economic platform, now virtually no one does. America has went so far to the right where a center left person from the 60's(on economics) is seen as an extremist. She's not more far left than Bernie but people also are using her youth and way she speaks as a way to slander her, not very easy to slander her on the facts. 70% top tax rate is common sense, to not agree with that is to agree with Reagan's treasonus reversal of that policy which was an intentional attempt to underfund the government. The planet being screwed in 12 years again is referencing scientists who say if we don't fix the problem by then we are probably screwed to a certain extent especially by the previously established 2 degree standard of being screwed. Trump on the other hand has been wrong on virtually every policy and the one's he's been right on he's had people around him work 24/7 to get a retraction(look at Syria, look at anti free trade which is a complex issue but being uniformally pro free trade is wrong). So on facts comparing Trump to AOC is just wrong because she does stay loyal to the facts. That line she gave to AC might seem anti fact but it doesn't correlate with her actually saying false things.
AOC is an inexperienced congresswoman, probably unqualified but you know she's still right on policy and like what 80-90% of the Congres are different degrees of economically conservative? We can't be picky because we've had to fight a war to get like a dozen real politicans who don't support the insurance industry and who don't support debt reduction. She was even citing MMT and I'll take that, when no one else more qulified on paper is.
