Fred the "Friendly Ghost"

There are three top-tier candidates and one ghost. So why doesn't Fred announce his candidacy? Maybe he doesn't have the money to pay for the balloons and confetti! Rumor has it that Fred may have only raised 3M.

Wasn't Thompson supposed to announce over the fourth of July? Where is this guy? Is he just hovering around somewhere? Is he even alive? Maybe what we are seeing is old video clips...or maybe he is a computer generated candidate. C'mon Fred! The water's fine!
