From what I recall of it, he basically began parroting all of the well-worn PDS talking points about her, with a 'concern troll' attitude for flair.
Someone else may chime in with the specifics, but in a nutshell, he's now closer to being a detractor, rather than a supporter.
Last thing I see on google is that he defended the Tea Parties and Sarah against attacks from his goofy brother. I hope that this is wrong. You won’t ever hear Rush or Levin talking silly trash about her. Bob
