I agree with her on very little, and I think she's a great figurehead for Republicans to use on Democrats, given her far left positioning.
However, I think its absurd that anyone would still question her talent. She's not perfect, she makes mistakes, but Republicans pretending she is dumber than she really is, or that she's not really good at her shtick, is just silly.
Her communication ability and charisma is so far ahead of the squad...I have a prediction. I think at some point she breaks to the center. It might not be all at once, it might be gradual. But at some point she will pivot closer to the mainstream and sell out the rest of the squad. I don't think she would be wrong to think she should have national ambitions, and that won't work from where she stands right now.
