Everything hinges on the Georgia election. If the Dems sweep Georgia, the present day architect of the Dem Party, yes, AOC, will be in an exalted position. She could make a play to displace Pelosi and maybe just knock her off. SHe is chimping at the bit for such a likelihood.
If the Republicans retain the Senate control, then AOC will be just one more big mouth that gets patted on the head until the Dems can gerrymander her out of existence in New York.
