Until she gets into the big under the table payoffs, she’ll have to stay within the script or she’ll lose her shoe allowance and the handlers are the ones getting her those 2 dozen headlines a day.
In the sense that they wrote the Green New Deal sure, but it's her own wackness that gets her the airtime and headlines. Without her, it's just another stupid piece of ill-conceived legislation.
Soon she will be big enough to pick new advisers and staffers and make her own connections if she wishes. That she'll chose wisely, though, doesn't seem likely. I think she'll stick with the same team, but they realize that they need her as much as she needs them.
She was an against the odds shot. Most of the Justice Democrat candidates lost. They could look for another front person to be their mouthpiece, but there's no guarantee that the new face would have the same success as Ocasio-Cortez did.
