Not declaring openly is a different animal entirely from not knowing whether you're running. Did you ever consider that there are strategic and tactical reasons why he may not wish to officially declare yet?
The man has filmed shows and a movie that cannot - CANNOT - be aired if he's a presidential candidate, without the same networks giving equal free time to all of the other candidates. That he's giving consideration to those who hired him, and who staked money on the ability to air those programs, says a lot positive about him. Further, he's also getting a lot of free publicity by subbing for Paul Harvey and for speaking on/writing for ABC. He'd be stupid to give that up. Also, he's letting the other Republican candidates hang themselves in their contradictions. Finally, I've heard that he wants to declare after 6/30, so as to start the 3rd quarter fresh (from the standpoint of campaign fundraising) - it'd look bad if he filed a 2Q report showing 1/3 or 1/2 of the fundraising shown by the others.
Again, these are tactical and strategic reasons for not declaring, not any kind of indeceisiveness about his ultimate candidacy.
It’s like saying when a college basketball sophomore doesn’t declare he’s entering the NBA draft in the middle of his NCAA season, he’s being indecisive. He has strategic reasons for not declaring. He has legal reasons for not declaring.
