Sources: Palin unlikely to announce at Iowa tea-party event on September 3

Still, Palin’s speech is expected to offer more clues about whether she will jump into the race sometime in September, as some of her public comments and behind-the-scenes actions over the past several months have suggested is possible. And a core group of self-appointed volunteer organizers hope that the Indianola shindig will be one of the best-attended events of the presidential campaign season to date.

“It’ll be big,” vowed veteran Iowa GOP grass-roots organizer Susan Geddes, who helped launch the Palin event.
