Palin's tweet was the first I saw of this news.
I've already seen a number of Lefties complaining the press are comparing Ferraro to Palin and not Hillary, ignoring Hillary wasn't even considered for VP let alone chosen. While Hillary achieved a lot in her own campaign, nearly saving us from Obama, she came up short of being a nominee.
I enjoyed Ferraro on Crossfire. She seemed like a principled Liberal, a breed that is all but extinct among Democrats today.
Relative to either Palin or Ferraro, Hillary is nothing.
