Yup. Your typical Dem criticism of another Dem is something along the lines of:
She didn’t do a good enough job of getting her message out.
She didn’t show people the wonderful side of her because she is so attentive to policy details.
She couldn’t be heard over the right-wing noise machine.
etc.
Or even, maybe she should have spent more time in the Rust Belt states. (Which is a smart criticism, BTW.)
