Warren Stupid? She sure didn't appear to be stupid at her rally in Va. Her problem was that most people are still not ready to vote for a smart woman who speaks her mind and persists.
Trump totally outwitted her, which says it all.
You have her up on stage boasting about her tiny fraction of maybe Native American blood while all the tribes are telling her to shut up about it. Her whole history with abusing that designation - which she has no right to - is something any sentient person in her position would be trying to brush under the rug. Not Warren, though.
It's like if Harris brought a black guy up on stage, emptied a pistol into him and planted a gun on his corpse with a saucy wink to the audience. Just because you're about something, it doesn't mean you have to put it up in neon for the whole world to see.
