Many American want a public healthcare option like we have here and a livable minimum wage. Many want greater response to the environment and the wealthy to pay higher taxes with the state not supplementing their profits (i.e. Bezo's tax proposal). AOC touches these core issues that most mainstream politicians do not given their financial backing by these core groups in politics. That is where her strengths are and people should not be dismissive of this as non-issues and that she is a crazy as they miss the bigger picture to her pulling power. All I am saying is people should be so flippant of what she brings.
Rand unfortunately needs to be tougher like his dad especially on foreign policy, the growing police/surveillance state and individual liberties. Tulsi is a realist and fighter that's why I love her bravery to stand up to her values and I find her agreeing with many of the issues the people want, not what business wants.
