It’s a weekday, which means that Jeb Bush’s presidential campaign isn’t going very well. He’s stuck in single-digit polling territory and his favorability ratings are poor. He’s running around defending himself after saying weird things about black people. His backers, financial and otherwise, are pressuring him to either make a move in the polls soon or be fed to a pack of feral dogs in a Fort Lauderdale alley. It’s always one thing or another for the Joyful Jeb! campaign.
