Sarah Palin is apparently not done with politics. It seems she has decided to strike out on her own, campaigning for all those who share her views of politics - which one would assume means "real Americans," though she does claim that she's going to campaign for Democrats as well.
What I found interesting about the article linked above is John McCain's assessment: "I don't think she quit. I think she changed her priorities."
While some might claim there is room for semantics here, the fact is that she campaigned for, and was elected to, the governorship of Alaska. She made a commitment to serve out at least one term. On July 3, she made a rambling wreck of a press conference where she explained that she was leaving prior to the end of her term, though she never explained why. According to dictionary.com, what that means is that she is, in fact, quitting. Definition #3: "to give up or resign; let go; relinquish: He quit his claim to the throne. She quit her job."
So, either Senator McCain is unaware of the plain definition of quitting, or he is trying to help salvage his tattered reputation for having so recklessly chosen this farce of a politician as a candidate by attempting to manufacture a plausible explanation for her giving up on her state.
