Ann Coulter and Laura Ingraham took a series of brutal swipes at Sarah Palin on Tuesday's "O'Reilly Factor."
Ingraham was filling in for Bill O'Reilly, and she and Coulter agreed that Palin has outstayed her welcome.
"She's become sort of the Obama of the Tea Party," Coulter said. "She's just 'The One' to a certain segment of right wingers. And the tiniest criticism of her -- I think many of your viewers may not know this. No conservative on TV will criticize Palin, because they don't want to deal with the hate mail."
Ingraham said that Palin is too thin on policy to be a credible presidential candidate. She said people were "desperate" for "real substance" and that Palin doesn't seem "all that interested in digging really, really deep on that stuff."
Coulter said that Palin's die-hard fans were becoming a real problem.
"You know, we used to all love Sarah Palin, conservatives like me, for her enemies," she said. "I'm starting to dislike her because of her fans." She added that, "it's true that liberals will call even smart conservatives stupid. That doesn't mean that when a liberal calls you stupid it makes you smart."WATCH: MORE
