Well, moving a show around and frequent breaks don't help to keep a new audience. But the breaks seem to have been mainly due to the original producer trying to do everything on the show and falling way behind in filming episodes. The postponement of the remaining episodes to the summer is probably due more to ABC trying to finish strong for the year with the final sweeps starting.
Of course, the sheer silliness of the show is clearly obvious even to the Hillary-loving executives at ABC.
