Paul says no kiddie table for him...

Remember right before the CNN debate Paul said he had an announcement to make, and some in the media thought it was a drop out thing. It was probably that he wasn't going to go to the kiddie table. And maybe CNN got wind of this and changed their rules literally at the last minute because they didn't want Paul's demotion and refusal to become the story, and because they knew Paul is good for at least one dramatic debate moment.
And maybe Paul thinks he can bully his way into the next debate too, but I don't think it will work this time.
The people determine whether you are a first-tier campaign, and the people are clearly not interested.
