Shelby Blakely, executive director of the Tea Party Patriots’ online publication, New Patriot Journal, said Palin’s endorsement has become “so undependable, it’s marginalized itself.”

While she once thought highly of Palin, Blakely said that over the past two years the “Going Rogue” author has gone more establishment, and Palin’s failure to criticize her own party is bothersome. “There’s room for criticism (all around),” Blakely said. “If you’re not willing to call it where you see it, that’s useless.”

Blakely said she believes Palin will endorse the most conservative candidate she can. But when there’s a party establishment candidate in the running, or one who had some ties with the McCain-Palin 2008 ticket, “she’ll go with that,” Blakely said. She points to Palin’s pick of Fiorina — who is “not conservative” — as an example.

“You never really know WHY she’s endorsing someone,” Blakely said. “It’s almost becoming a nonfactor.”
